Thanks for your help. I've sussed it! Load image, unlock, select move tool, hold control key, drag right (or left) circle until correct, finally, document->unclip canvas. The last step fixes the canvas size!

Ah ha! thanks for this. I've made some progress. Turned out images are locked when first loaded. That's why the move tool didn't already work. So unlocking the image, allows move to work. Indeed i can widen, and make other transformations, but the image remains the same canvas size. How would i widen and increase the canvas width also? Thanks for helping.

Sorry if this is a really dumb question, but i can't seem to find a way with Photo; I want to widen a image by dragging with the mouse. How to do this? Thanks for your help.
