Is there a way to choose how many photos is presented at once? If so I can't find it. For me it would be great there was an option of loading more photos at once. I would rather scroll down to see a zoo's whole gallery then constantly be clicking "next".
At the moment, no there is not a way to do this. There is a new version of the forum software and photo gallery coming early next year, not sure what they are planning on doing there.
