Crop tall .jpg to square WITHOUT complex cropping add-ons
I have a handful of jpg files that are tall and vary in size. I want the excess length to be trimmed (so aligned top-center and cropped to a square) but I don’t want to add any extra systems like thumb.php, ImageMagick, etc. to the page because simplicity and file-size are important for this quick project.
They are [I]all[I]all
Any advice or help would be greatly appreciated.
