Thanks for the tip. I already had a peek at Photo.py and found out how prevPhoto and next Photo were created. But playing with this code is a bit "out of my leage" with no starting clues. Maybe if I had a week ar two to spare I might get around with it. But I can't get them to pay me for two weeks "on the job training" :-( . WOuld be nice if they did. Got any hints how to do this within a days work? TIA, Roel. PS I'm no programmer but I'm eager to learn

Now here comes my problem: prevPhoto() and nextPhoto() are retrieved from a python script and calculated from the image shown at that moment. How can I resolve 'PREV' & 'NEXT' filtering with the metatag? If I use if - elif -else - /if 'PREV' and/or 'NEXT' are not shown if they have an invalid metatag.
Is there a solution to this?
The nextPhoto and prevPhoto methods are simple convenience methods, but they don't do any filtering. You'll need to create your own next/prev scripts to filter out what you need and return the proper next/prev object reference. I suggest the nextPhoto/prevPhoto source in Photo.py as a good starting point. _______________________
