I installed this extension, basically because I was tired of my users not having an image in their profiles. This solved that problem quickly! Now, if they get an automatically asigned avatar, unless they upload their own pic ;) Besides that, you can display a module showing the latest users, users online, and a lot of other possibilities.

My only suggestion is that it would be great if we could choose .gif avatars, besides .jpg (at this time they can be uploaded as jpg), since this way you could upload animated gifs and, when images have no degradation colors, they are better displayed in gif and have smaller size.

I highly recomend it with CB.

PD. Also, when I had a problem, I received a fast an excellent support from the developer :)
