Maggie Dennis on bug 50645:

I'm not sure if this is the same issue, but as reported on English Wikipedia
and tested by myself, using the image resizer to "Make full size" resulted in
either a notice that no change had been made or a silent failure to save.

This was tested on FF26, W7 and Chrome 32.0.1700.107 m, W7.

The reporting editor concludes that "These new settings, for what they are
worth, only work if the image already has a size indication (200px,
250px*250px, whatever), not when it only has a 'thumb' indication. Sadly, the
latter is the default and by far most common situation."

He also questions the purpose of "Make full size", but I'll report that
separately.
