One of the problems with taking snapshots inworld without saving them to your hard drive first, and then downloading them as texture files is that they are not saved to the correct dimensions. Take a look at this photo of myself dating back to 2007. It was first taken as a snapshot inworld. My face looks unnaturally thin.
This can of course be fixed in Photoshop. But I found a much faster way to do this, using the free Fotoflexer
onine photo editor, go to the resize area, and make sure keep proportions is not checked. The use percentages tab is optional. And you can see below that I was able to get the right dimensions for this photo in about the same time it would take to open Photoshop. Fotoflexer has other cool effects you can experiment with but it is the easy resizing that makes this one stand out.
All you have to do is upload a photograph (no registration is required)
