Did you try this option from their tutorial?

Quote:
Click Save a copy at the bottom of the page to create a new image in your account, with the modifications that you made. Photobucket recommends this option if you want to keep your original image unedited. Click Replace original to save the changes you made to the original file in your album, replacing your original.


If you resize it, save it, and use the correct link to it, it will appear here the same size that it appears on Photobucket (assuming you are viewing both sites with the same browser setting).
