Today I have been investigating PayPal. I set up an account and then I figured out how to add a gift certificate button - you can check it out in the left column. I would be nice to customize it but at the moment I have no idea how to do that! I can also now send invoices via emal that you can pay with your credit card thanks to PayPal - you do not need a PayPal account to do this.
I would like to figure out if I can make the slide show random. It starts on the same pictures each time. I'd like it to mix things up so each time you visit it is on a different picture. More research!
