It was Steve Saunders from elertz that told me about SnagIt. You can download it here.
SnagIT lets us copy anything we can see on our computer screen so that we can paste it later as an image. I used the free trial for a while and then reluctantly paid for a license and so started to use the additional features - cropping the images I have copied etc...

This was very useful for me as the reports that I need to generate for require me to merge the graphs etc from different sites and paste them into Microsoft Excel 2007.
