Since updating to Lion the Automator workflows I've created to resize images have stopped working properly and I can't figure out why. It's a simplish workflow that works on folder input, gets the folder content and uses an applescript to copy the files to a different folder in the parent folder. It then changes to the folder, gets the folder contents and runs the scale images to a given pixel size. Everything used to run fine until the Lion upgrade, now I find that it always stops at a point during the scale actions which seems to be at the 174th image. I've tried renaming/moving images around to see if it's a problem with an image but that hasn't helped. Can anyone suggest any other troubleshooting steps?
