Well I have never experienced that problem before, but I have looked up problems concerning it and it seems it has something to do with file extensions, which are basically the file format your picture is, so for example a file extension would be JPG, PNG and so on. Seemingly when you get a message such as illegal file type, it means that the file extension you have tried to upload isn't recognised by the wikia. (as different wikia's may not have the same file extension's programmed into them)

Now while this seems like a simple problem you did say that they were GIFs, which should be able to be uploaded on here, as I've uploaded a fair few GIF's myself. All I can really suggest is to check if your pictures are GIFs, try and if it fails, try and upload them in a different format, such as PNG to see if it isn't another problem.

I'm sorry I couldn't help you out any more than this, but this is the first time I've encountered a problem like this as well.
