I've been working on some scripts that will apply an effect to a tube or photo. Firstly we have a Metallic Effects script that comes with patterns to give a gold, silver, copper or bronze effect. You can adjust the script to show as much or as little detail from your tube as you choose.
The second set of scripts are for paint brush effects. The Brush Effects script changes your tube or photo to make it look as if it has been painted. You can adjust the brush stroke to suit your project. The Soft Pencil script gives a lighter almost watercolour like effect to your tube.
Finally to the FREEBIE - a Sticker maker script. This script will turn your tube into a sticker either with a flat finish or a puffy finish.
PLEASE NOTE - this script is not suitable for tubes larger than 1200 x 1200 pixels. This script can also be a bit fussy if your tube is an unusual shape because the white fill is at a fixed point (dead centre of the 1250 canvas). One of my PSP11 testers also had trouble getting the script to work. Best results are obtained if you don't change the canvas size and you make sure your tube is centred.
