I am trying to find software that would allow visitors to
upload a photograph(s) to see how they would look in selected
greeting cards or frames. I have the greeting cards scanned and
saved in .PNG format with a transparency window for showing the
photograph but I need to find a tool that would allow the image to
be resized or cropped by the visitor - to best fit the opening in
the frame or card. Any thoughts on where I should look or start?
