As you can see from my forum post and work-around, I was having the same old problem everyone has regarding linking to a Lightbox show from one image or link. See here. I dislike intensely NextGen Gallery so I spent ages finding a solution. Whilst I am sure there are a number of work-arounds out there, the only one that has worked for me so far has been to use this plug-in and the display:none style on images (I've included a walk-through on my post). I give it five stars for preventing me from pulling out the rest of my hair.
I know this is the nature of the prettyPhoto look and not so much the plugin itself, but I would like edge-to-edge images. PrettyPhoto always reduces the images by slapping large invisible margins round all four sides. I'm going to attempt to hack the css to over-ride this but if you could include this as an option in the next version, or msg me to let me know a work-around, I would be very grateful.
In the meantime, thanks for a plug-in that actually works and keep up the great work.
