Forum:Avatar Uploading

Hey there, I'm not sure if this is the right place to ask this, but I haven't found any other place which seems more relevant for this problem.

Anyways, I have a problem uploading an image for my Avatar and I've got completely no idea why. When I double click an image which I want from my desktop, the name of the image appears for about a second, and then disappears. I tried leaving it for a while, and then clicking - "Save, I'm Done" but it just wouldn't work. I'm trying to upload a .jpg image, perhaps this could be the problem (even though I'd highly doubt it)?

I really want an Avatar image and I've been trying to figure out the problem for a couple of weeks now on my own, without too much luck as you can see.
