I try not to, but i did wonder about that, because once I save it in the computer programme it's a Serif file (goodness only knows what that does) and will only save in another file as an export. So then I export it as a jpeg and crop it in my basic software (which is better at that, and also doesn't lose the quality so much.) I'll have to have a play with that. What sort of file types should I be looking for? (If I don't have them, I'll just experiment, but I knew that jpeg was potentially problematic, but not which file type is better.)

Thanks. :-)
