If I had to do this I would probably waste a couple of hours fiddling with various baffling menus. Have you noticed how so many computer programs never seem to have options for the obvious? You want to do something reasonable - like saving a piece of text as a jpeg - and the only options that seem to be available are about as relevant as inserting a crocodile into and onion! Then it turns out that all the obvious things are hidden away in sub-menus of sub-menus and are invariably 'greyed-out' when you eventually find them.

In this case I would probably end up printing out the piece of text, scanning it back in again and saving the resulting file as a jpeg. Pathetic, I know, but saves an awful lot of aggravation!
