Download resized image

[nickelas]

I am lookin for a plugin that (on the fly) resizes the full image to a size specified by the user and lets him save that   I find that with a huge full size image, it would be handy to be able to download a not watermarked image in a size you can choose yourself. So I am hoping this is possible:
Specs user:

• Button "Download resized image" below the intermediate pic.
• Opens a new window with the thumbnail and a form.
  
• User can enter numbers to specify the width or height, choose between 72 and 300 ppi and choose sharpen: low,medium,high.
• Press ok and a save-dialog is shown for the resized and sharpened image

Specs admin

• Enable to: all,only logged in
• Put watermark for users: everyone, guests only
• Enable a log with user, pid, time, settings

Language-file for the button-text, form and save-dialog. Store the generated image-file in a specified folder and if possible delete it after the user has downloaded it.

Budget: 50 $. I know it aint much.
No real rush though.

The specs are ideas and open for discussion. Plugin would be made available for download in the proper place.
