Question What is the Composr Member System?
Answer The Composr Member System is the system used by the Conversr forum software to manage user accounts and information. This includes usernames, passwords, profile information, and usergroups. It also handles user registration, login, and account management. For websites not using Conversr, the member system of the third-party forum software would be used.
Question Can I Use Composr Galleries to Publish Podcasts?
Answer Yes, Composr supports creating podcasts from galleries. The podcast URL follows this format: http://yourbaseurl/backend.php?mode=galleries&select=galleryname&type=rss&itunes=1. Replace yourbaseurl and galleryname accordingly. This URL can be used to subscribe to the podcast in iTunes or other podcast applications.
Question How Do Gallery Slide-shows Work?
Answer When viewing an image or video in a gallery, visitors can initiate a slide-show that automatically cycles through subsequent entries. The slide-show can be paused with a click or keypress. The default slide-show speed can be adjusted by modifying the GALLERY_ENTRY_SCREEN.tpl template.
Question What are Watermarks and How Do They Work?
Answer Watermarks are semi-transparent images overlaid on gallery images to mark their origin or deter unauthorized use. When you add or edit a gallery, you can choose to apply watermarks to the corners of images. Watermarking applies permanently to the uploaded image. Composr uses a reverse tree structure for watermarks: if a sub-gallery doesn't have a watermark defined, it inherits the watermark from its parent gallery.
Question Can Members Create Their Own Personal Galleries?
Answer Yes, members with the "have personal galleries" permission can create their own galleries. These personal galleries are displayed under designated "Personal category container" galleries. They also show up in a tab on the member's profile. Members can only add content to their own galleries unless they have the "Submit to categories belonging to other members" permission.
Question What are Rep-Images and How Do I Set Them?
Answer Rep-images, short for "representative images," are thumbnails that represent a gallery when it's displayed within a list of galleries. They offer a visual preview of the gallery's contents. You can set a rep-image when adding or editing a gallery, or when adding an image to a gallery.
Question How Do I Import Images in bulk into a Gallery?
Answer You can import images in bulk using a CSV file. The file should be named descriptions.csv and placed in the uploads/galleries directory. The first column should contain filenames (without the path), and the second column should contain descriptions. The filenames should correspond to images also located in the uploads/galleries directory. Composr will automatically match the descriptions to the images during import.
Question What Image and Video Formats are Supported?
Answer Images:
  • .jpg/.jpeg: Highly compressed, best for photos due to minimal noticeable quality loss.
  • .png: Good compression with no quality loss, ideal if bandwidth isn't a concern.
  • .gif: Limited to 256 colors and poor compression. Better alternatives are video or APNG.
Note that Composr does not support SVG because hackers can leverage the XML-like structure of SVG files to compromise a website.

Videos:
  • .mp4 (h.264 aac encoding): The recommended format, widely supported.
  • .mov (h.264 aac encoding): Identical to .mp4.
  • .webm: Supported natively in most browsers, but requires plugins for Internet Explorer/Microsoft Edge and Safari.

Other formats, while they may work, are generally discouraged due to compatibility issues and lack of consistent addon or browser support.
Question What are Composr Galleries?
Answer Composr Galleries are a system for storing, organizing, and displaying images and videos. They function like categories, allowing you to group related media together. Galleries can be structured hierarchically, with sub-galleries nested under parent galleries, similar to a folder system. Each gallery has settings that control its appearance and behavior.
Question How are forums structured in Composr?
Answer Composr forums are organized hierarchically:
  • Forum Groupings: Broad categories that contain forums.
  • Forums: Contain topics related to a specific subject.
  • Sub-forums: Forums nested under other forums, providing further categorization.
  • Topics: Threads of conversation containing a series of posts.
  • Posts: Individual messages within a topic.

Question What is Tempcode, and how is it used in website themeing?
Answer Tempcode is a templating language used within Composr. It offers a powerful way to control the output of dynamic content and design elements on a website. It works by using:
  • Parameters: Placeholders for content passed to the template from Composr / PHP.
  • Symbols: Global functions that perform operations, calculations, or retrieve information.
  • Directives: Instructions that control the flow or logic of content, such as conditional statements and loops.
  • Language strings: References to pre-defined text stored in language files for easy translation.
  • Escaping: Ensures the content generated is properly escaped according to its use case.

Tempcode empowers theme designers to create highly customizable and dynamic websites, allowing for logic, conditional rendering, and manipulation of various website elements.
Question What are some alternatives to Photoshop for web design?
Answer While Photoshop is a popular choice, there are other excellent options available, including:
  • GIMP/GIMPShop: These free, open-source image editors provide a robust set of features comparable to Photoshop.
  • Paint.NET: This free, Windows-only software offers a user-friendly interface and essential image editing tools.
  • Corel Paint Shop Pro: A more affordable alternative to Photoshop, Corel Paint Shop Pro delivers a good balance of features and ease of use.
Question How can design elements like dominance and attention to detail improve a website?
Answer Dominance and attention to detail are key to a balanced and engaging website. Important elements can be emphasized using techniques like larger text, unique colors, and increased spacing. Conversely, less crucial elements should receive less emphasis. This interplay helps guide the visitor's eye and ensures a visually harmonious layout.

Attention to detail involves eliminating inconsistencies and distractions, such as typos, misaligned elements, and low-quality images, that can detract from the overall aesthetics and message of the website.
Question What is the importance of color schemes in website design?
Answer Color schemes are crucial as they convey emotions and brand identity. Choosing colors that align with your website's purpose can evoke desired feelings in visitors. For example, a website selling chocolates might use shades of brown to subconsciously trigger associations with chocolate. However, an environmental website would be better suited using green, aligning with pre-existing perceptions of environmentalism.

It is also important to maintain consistency with your color scheme, limiting the number of colors used to avoid a conflicting and cluttered appearance.
Question Can I use Comcode / resource IDs directly when working with the repository?
Answer Using Comcode / resource IDs directly is not recommended as they may not match between different sites. Use GUIDs instead, which Composr automatically substitutes for IDs before parsing Comcode. You can use Commandr commands like find_guid_via_id to find the GUID for specific resources.
Question What precautions should I take when using the Composr Repository?
Answer Exercise caution when working with the repository:
  • Avoid using it as the sole backup method; rely on regular database backups.
  • Work primarily under the "var" meta-filesystem and copy specific folders/files rather than the entire repository.
  • Do not use tools like "rsync" or Git on the whole repository without careful consideration.
Question What are the limitations of the Composr Repository?
Answer While powerful, the repository has limitations:
  • Automatic syndication is not performed for content added via the repository.
  • Multi-language content translations are not retained.
  • Transferring complex data schemas between staging sites may have limitations.
  • Merging separate websites into one is not supported through the repository. You should use Composr's import tool instead.
Question How can I access the Composr Repository?
Answer You can access the repository using WebDAV (non-bundled addon), which allows you to view it as a folder on your computer. Composr uses the SabreDAV PHP library for WebDAV functionality. However, please be aware that SabreDAV is deprecated and may not function correctly on newer PHP versions.
Question How is the Composr Repository structured?
Answer The repository is structured as a filesystem with various meta-filesystems mounted under a root directory. These meta-filesystems include:
  • bin: Stores Commandr scripts.
  • database: Provides access to the raw database.
  • etc: Allows access to Composr configuration options.
  • home or filedump: Provides access to the File/Media Library.
    • home contains the files in a special JSON format with metadata
    • filedump contains the raw files
  • members: Lists registered members with their settings and user groups.
  • raw or root: Provides access to the Composr installation directory.
    • raw contains the raw files without overrides, and modifying any file modifies them directly without automatic override handling
    • root contains the files with applicable overrides applied automatically, and Composr will automatically handle overrides and utilizing _custom directories when these files are modified
  • var: Contains structured website resources and content.
Question What are the benefits of using the Composr Repository?
Answer The repository offers several benefits:
  • Opacity: Provides a clear view of Composr's content and resource data.
  • Tactility: Allows easy manipulation of data through drag-and-drop operations.
  • Data transfer: Simplifies transferring data between sites.
  • Desktop application integration: Enables using text editors and file-search tools for tasks like mass search and replace.
  • Configuration management: Tracks changes to options and facilitates transfer between sites.
  • Backups: Allows backing up portions of the repository.
  • Revision control: Supports built-in and advanced revision control.
  • Filesystem for Commandr: Acts as a file system for the Commandr command line.
  • Resource API: Offers an abstract resource API for programmers.
  • API for external apps: Provides an API for mobile apps and other external applications.
