Note to yourself in future, when you open a picture file in either paint shop pro or photoshop, always tell the software to create a 'duplicate' picture then your not working on the original and it will ask you to save as it's a new image.
Paint shop pro - 'Tool bar tab at top -> edit -> 'Copy' -> Tool bar tab at top -> edit -> paste -> 'As new image' (or CTRL-C -> CTRL-V)
Photoshop - Open image, right click on top bar of image -> Duplicate -> 'ok'
Saves the hassle of loosing the original
