I have 50 old family photos of varying sizes that I have scanned in from various sources all over the USA. I want to print a set of all of them as 4inch x 6inch prints on Walmart's online photo printing. But when I upload them all to a Walmart album, it crops them instead of adding whitespace to the canvas. Cropping messes most of them up, I need a way to get the entire source photo and automatically stretch the canvas to fill the rest of whatever dimension is too short.
Is there any way to do this in Visualizer Photo Resize? If not, do any of you know of another tool to resize the canvas for this type of project?
Thanks very much, and my elderly uncle will thank you too if I can get him his set of prints
