Now that I am playing around with it a bit, I see it doesnt always show a picture?

I have noticed a glitch, I have my random image block above my section menu and now the Header title text "Section" links to my photopost? see here, www.flyfishbc.com

I fixed this by removing this,

Excellent, thanks for the post. Was looking for a widget like this. The plugin on the Photopost site generates a film strip in the forum and a profile reference. Slightly too much for my taste since there's no config/controls.

Aside from the db prefix and the relative path, I had to tweak href=\"photos/showphoto.php/photo/" to href=\"photos/showphoto.php?photo=" in order for the link to the actual picture to work, but it was up and running within 5 mins or less.

Excellent, that edit also fixed the issue i reported earlier :up:

working great thanks :) 5* :up:

Yeah, the thing is that there seems to be two ways that the URLs for photos seem to be generated (SEO friendly and not.) The vBSEO rewriting the gallery URL's also made it a bit harder to troubleshoot. Then I clicked on your image and saw you had fixed it before I got to you! Glad it's working for you now!

So what is happening here is that the script is selecting a valid photo in your photopost database, but the thumbnail and possibly the full size photo don't exist on your server.

Look at post #4 (and the replies) in this thread.

Is it possible make it show only certain category photos in the gallery instead of selecting from all category in the gallery and showing them?

Yes. It's a matter of adjusting the SQL query that the script uses to find a picture.

This post in the original authors thread might point you in the right direction.
