Jason Snell on Six Colors: Resize and upload images with Acorn and Transmit

"The script loops through every file selected in the Finder, opens them in Acorn, resizes them to the two sizes (or their equivalent sizes if they’re vertical rather than horizontal images) and saves out JPEG files, then uploads them via Transmit. It’s quick and dirty—if anything in the file’s name or path contains a period (other than the filename itself), it won’t work."
