I am finally back from vacation and took the opportunity to upgrade the board to its latest version (3.0.9) and the same for the gallery (so it works when the board will be upgraded to 3.5.0 version. It is currently in beta version).
A new photo category has been created at http://www.megapixelworld.com/photography/index.php
It is named Digital Art. There we can post manipulated photos etc. Sophia will be able to show you the power of photoshop :D
