Why do you expect it to be significantly faster? You're still
transferring the same amount of info...

Yes

In PHP, the same way you shrink one JPG image (based around
imagecopyresampled()), except with a loop that reads through each file
in a given directory (based around readdir()).

Most professional graphics application sallow you to perform batch
operations with a macro. e.g. Photoshop has a "droplet" facility, which
creates macro executables which you can drag-and-drop batches of image
files onto.
