Firstly, you have to import the List Files script into your global.js:

http://dev.wikia.com/wiki/ListFiles

You have to do this to get the list of all your uploaded files name from this link (you can change the limit to get more images):

http://aselia.wikia.com/index.php?limit=50&user=Arosia&title=Special%3AListFiles

Secondly, import AjaxBatchDelete script

http://dev.wikia.com/wiki/AjaxBatchDelete

After some Ctrl F5 to make script works on your browser, you can copy paste all the files name you get from the link above and delete all of them.

Hope this help
