Image File Size Reduction

[Jacques Hausser]

I don't know fi it's the best way, but in one of my applications, I drag and drop an image and retrieve only it's file path (e.g. : put the dragData["files"] into photoFile); then I set the filename of existing empty images to this file path, adjust the size as needed (in reference to rectangles on the card) and export them "as jpeg" (and so I get rid of EXIF metadata). For the colors, I don't know...
