I know lots of people don't have some webspace of their own. However, if they start posting on forums etc, they tend to want a nice picture with it. So they do a quick Google image search on it, paste the uri of the picture in their profile, and done. Results here and here, for example. Mind the picture of the guy with the cup of coffee. I borrowed that picture from Alextreme's posting about the same problem. In my case, they where linking to the small DeviantArt and Hacker emblem logos [both can be found in the bar at the right of this site], but it's about etiquette. You shouldn't misuse others bandwidth and resources this way. So, having some fun now with renaming a few pictures :)
