I tried checking the MIME type for the pictures, and they all returned this message:

The MIME type for your file is: image/png

I was trying to upload the pictures as new versions of the pictures that are currently on the wiki (the new versions are higher resolution compared to the originals) by going to the image's page and clicking "Upload a new version of this file".

Even using Special:Upload itself results in the error message popping up over and over again.
