Assuming that people want to download the smaller versions of images, those versions need useful file names.

Currently the names are just "medium.jpg" and "thumbnail.jpg", which are not unique.

Better names could be something like "Original_file_name.medium.jpg". However, it attention needs to be paid so that GMG does not try to create files with paths too long for the operating system to process.

Currently media deletion happens like this:

1. Go to media page.
2. Click "delete".
3. Check the "I am sure" checkbox.
4. Click "delete permanently".

If the checkbox at step 3 is not checked, you are back at step 1 (the media page appears untouched).

MediaWiki and file managers do it differently: you don't have to use a checkbox, but only click another button.

When the checkbox UI is used, but the deletion is cancelled due to the checkbox being unset, a message should appear to the user, or he might think that the deletion simply failed.

P.S.: I suppose that checkbox is there because people used to deleting (or running a bot) may click through many buttons and accidentally delete stuff. However, when everything uses a checkbox, it will just slow deletion down and make the user get used to that longer path. There should probably be a way to delete larger arbitrary groups of media quicker, at least where it is possible to upload large amounts of media.

Looking at the code, it seems like the comments (on a media) aren't deleted together with the media.

• If the code exists, point me at it, so I can possibly add comments, so I'll find it next time easier. AND: Maybe there should be unit tests for the comments being deleted?
• If even those unit tests for comment deletion exists... Oh well, Reject this bug.
