Well done Mike - I think you'll be happy with them. As with any software, there are a few "gotchas" - so just start a thread here if you need help - I've got most things sussed with regards to Pbase basic operation.
Probably the biggest is - if you want to direct link to an image, click edit image, and copy the URL from the top/right area of the screen - DON'T use the URL in the address bar, or only you'll be able to see it!
Whenever you copy an image URL from the edit image page it'll always end in medium.jpg - that's quite low res for here, so be aware that you can change it to large.jpg or original.jpg. Personally, I always upload images with the long dimension being somewhere in the order of 1000 pixels or slightly more, and use Photoshop compression 10 out of 12 (or whatever it takes to get it under 500kb) - that way you'll have room for over 2000 photos if you're on the 1GB plan.
