Photo Gallery modification

Hi, my gallery: [login to view URL] 1. When viewing the big image: a. Disable the "zoom" feature when the user clicks on the image. b. When user moves mouse over to left 1/3 of the screen, mouse cursor to display "[login to view URL]". When user clicks, display next image. c. When user moves mouse over to right 1/3 of the screen, mouse cursor to display "[login to view URL]". When user clicks, display previous image. d. When user moves mouse over to middle 1/3 of the screen, mouse cursor to display "[login to view URL]". When user clicks, then display thumbnail image list. 2. Reverse the direction of previous/next image display. Currently, when the user clicks on the "next" image or use the slideshow-feature, the images are showing from left to right. It should go right to left. 3. Remember thumbnail location: when viewing big image and user clicks to view the thumbnails, the thumbnail list should display the relative location of the thumbnail. thanks, John
