The VG Resource

So I resized the Rocket Knight Customs icon for The Spriters Resource, but not The Models Resource icon. The image has transparent sides on both.

Is there any way to undo this? Also here's the pics:

As long as you have the intended image prepared, a site staff member can fix it for you.

Unfortunately, from my experience, there's no way to do it yourself.

For future reference, you can make a post in the errors thread if something like this would happen again and a staff member can handle it for you: https://www.vg-resource.com/thread-27786.html
