If you're looking for some freeware which will help you create animated GIFs, ignore Cropper (found on codeplex here: https://github.com/brhinescot/Cropper ), and instead try the nice and easy GifCam. I tested Cropper. After I added the .dll file which were supposed to enable it to create animated GIFs and followed the necessary steps, in only allowed me to record a GIF for a split second. I don't know what was wrong exactly, but GifCam is worry free.
GifCam downloads as a single executable - you don't have to install it. The application will open as a separate window and allow you to frame whatever application you want to record.
You simply press REC, then STOP, and save your GIF. I create the below animated GIF with no trouble at all!
