This is a little PHP script that allwos you to backup/export your (Twitter) yfrog images. I was using yfrog for a couple of years now, but as time moves on so do I. I want to try something new and I think CloudApp will do just as fine.
You need to have an API key for this script to run, which you can easily get by applying at ImageShack. (yfrog is made by ImageShack) Requesting took mere minutes and I had my API key. Just edit the devKey and execute the script via:
php yfrog-backup.php YourUsername
The export path is optional.
