avatar exactly 100x100px and 4kb fails to upload

[Riki]

My avatar will not upload from home folder. It is 100x100px and 4kb.

In my case, the problem was that the extension of the jpeg image was in capital letters i.e. .JPG. I renamed it to .jpg and I can now upload my avatar. Hope this helps somebody.

I have no idea how the code is written, but it's better to check for mime-type rather than file extension. You can create a gif-file but name it 'test.png'. It's still a .gif-file even though the extension "tells you" it's a gif-file.

I don't know which language the site is written in, but in php it's quite simple to check with fileinfo().

I can confirm that the .JPG file extension rejects the upload - I've raised a bug about this, as it shouldn't really matter what the extension is for this image.
