I need something like this, this example is copyrighted so I can’t use that.
The script has to work like this:
I give the script an image url.
The thumbnail size should be variable.
I send the script the url with GET, like this: [url removed, login to view]://[url removed, login to view]
I can drag my mouse over the full size image and select a part to create the thumbnail. This drag box should be in the thumbnail x and y ratio.
After selecting I can click double on the selected area and the script will create a thumbnail using imagemagic and the script will write the thumbnail to the servers harddrive.
