Just a heads up!! If you have an animated icon that's 50x50, dA eclipse won't resize it for you (at least, not properly, and you can't upload anything smaller than 100x100 if you have eclipse turned on).
But the site I use to put my icons together does have an option for resizing!
ezgif.com/
Just go to the "resize" option, upload your icon gif, set the boundaries to 100 width and 100 height, and then choose Gifsicle for the resize method! It'll make your icon bigger without messing up the pixels~
Example:
So if your favorite icon is a 50x50 animated one, don't panic!
(if it's NOT animated, you shouldn't have a problem with the resizing, dA does that itself!)
Also, side note, I do NOT recommend making a 100x100 icon with single pixel thickness at this time. If you resize a 100x100 icon down to 50x50 it becomes a horribly blurry mess. It's best to keep using your 50x50 one and letting dA size it up! At least until everything is permanently settled with this site.
