I moved the thread down here, this is the better place for it 
That error isn't really clear about what's going on. I don't know that error and I don't have a clue how to solve this, but what I'd try:
- use an other browser (especially if you're using a less regular one right now)
- rename te file to somthing simple like avatar.jpg
- convert the file to an other format (gif, for example)
- try some other pic and see if that works out
Hope this helps
