I tried CaptureSaver a year ago and this is a good program for saving information from the Internet. Not only it is able to capture images but also texts from the screen and edit them thereafter. Sure, it is not as excellent as Snagit but still worth it to have CaptureSaver if you don't have Snagit yet.
