/**
* Ver 1.2
* packetmad October 14, 2003 www.lanside.net

* Blaine Lang March 21/02 www.langfamily.ca
* Ver 1.1
* This Geeklog PHP function uses the Gallery Random Block code contibuted by Bharat Mediratta - Gallery Developer
*
* The Gallery random photo block will display a random photo from your Gallery in a geeklog block.
* The photo is displayed along with its caption and clicking the photo will take you directly to that photo in the appropriate album.
* This version of the random photo code only displays public photos - for which gallery has granted everyboddy access.
* Once a day it scans all your albums to see which ones are viewable by the general public.
* Then it saves that data and uses it for the rest of the day.
* If you change permissions on an album, add or delete albums the changes won't be reflected right away in the random photo block.
* You must have Gallery v1.2 or better to use this block.
*
* This block will also display the photo caption. This is nice when you add comments as a photo caption
* But if you have not, the block may display the default photo caption which gallery defaulted to which is your digicam IMAGE ID
* I have added a check and exclude these captions. Modify this as required - about halfway down in this function.
