There's a reason for it.

For images/videos there'll always be a thumbnail, which can always be linked.

For downloads there may be a thumbnail, but may not. So we link it on the title shown in the box title.

I find linking in the box title a clunky necessary thing, I wouldn't want it to be on all of them.

If you want you can edit GALLERY_VIDEO_BOX.tpl & GALLERY_IMAGE_BOX.tpl...

<h3>{$GET,content_box_title}</h3>
-->
<h3><a href="{URL*}">{$GET,content_box_title}</a></h3>

Fair enough, but I think I will make that change so thanks for the pointer :)
