I've started using IrfanView for creating screenshots. I was already using IrfanView for displaying images in Windows but I was looking for a tool to easily create screendumps without starting Photoshop that is a bit too heavy for this purpose. I read somewhere that you could paste and crop in some Microsoft Photo editor and immediately thought that it must be possible to do similar in IrfanView and Presto! It was. The only annoying detail is that it's a bit hard to crop, but I usually do alt-print-scrn anyway so it's not to much of a problem. I just do "Create New (empty) image..." and then paste my image into that. It adjusts to fit automagically. Nice!
