I taught myself to do it. I have the background frame saved as "template" at a certain pixel size/DPI. Use the type tool to get your text on there and flatten, save as "template" or whatever you want.
Then, with a bit of trial and error I found the right pixel count at the same DPI for the photo inlays and always use that same size. I open my pic, image-->image size to the right pixel count/DPI, select all, copy, close the photo without saving (or ruin your full size), paste onto "template" then use the arrow tool to center it. Then I "save as" a JPEG with the photo name and I type "web" after it, so "brainweb" etc.
It takes some time to set up, but I've got it down, and really enjoy the many benefits of the frame. You can PM me if you have any other questions, or post them here and we'll have a little framing workshop.
Good luck!
