You have all those wonderful psps you have made or downloaded. Some of them are nice small matching ones that would make great tube sets. Well, it is very easy to do with the Auto Tube script in PSP8.
Fine a nice little set of psps that you want to put into a tube. Open them all in PSP8. Five or six is a nice number.
Your images need to be the same size. Pick a canvas size that will cover the height and width of the largest one. I choose 300X300 for mine. Image/Canvas size. Be sure the image placement is set for the center on the canvas. Do this for each one of your psps.
From the drop down scripts list selet Auto Tuber and click on the arrow right beside it to run the script.
The define cells dialog box will come up, the default is correct for this one. Click ok.
Now you have the export picture tube dialog. I have accepted the default for this one also and picked a name for my tube. If you are making a tube for a chain or rope effect you will need to change the setting according to what you want.
You can copy the PSP tubeimage as a .tub and use it in PSP7 if you want.
