I figured out how to save a pic to a web hosting site, and copied and pasted the url to the block where it asks for it in my profile. I then clicked on select avatar and it went back to my profile page where I now see my pic in the little box on the profile page. I have tried clicking on the update profile button at the bottom of the page, but the image then disappears. What am I doing wrong? My file size is 308 kb and it is a .jpg. Please help!
