I'm not a designer but I sometimes have to create/edit images for our applications.
In the past I've used "Microsoft Image Composer" - I like its user interface because it's object based and easy to use. Unfortunately it was discontinued and the old version I am using has some problems with png files.
I've tried to find a good replacement but everyone seems to be using layers instead of objects.
Do you know any image editors that are object based?
EDIT:
Still haven't found what I am looking for ... the best alternative so far is Paint.NET even though it uses layers.
