Third:A link for one of my favorite plug-in for gimp.It is called LIQUID RESCALE.You can use it when you want to remove something of an image,avoiding to much distorsion.Little bit complex to explain,go visit the site,check the examples,tutorials and manual.It sure worth the try,it's freeeeeee! [link]
Quatro:Why not videos!A links of a gentleman,Mortimer,working with freeselect tool,magic wand,layer masks.It worth the detour! [link]
In a way here is the most important link because it is the gate of heaven.It is the starting point of a life for beginner artist(like me).Here on DA there is a place called HOSPITAL LIBRARY where lots of artist put links for learning about everything.It is awsome,don't miss at the bottom of the page OTHER BANKS OF TUTORIALS.
