DISPLAY: JavaScript - Basically would like to have the same picture display as the link below. http://www.amazon.com/gp/product/B001JEOV8S/ref=s9_al_gw_ir01?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=center-2&pf_rd_r=14E23EFRVC7H9BPC2JTH&pf_rd_t=101&pf_rd_p=485230251&pf_rd_i=507846 A large thumbnail picture displayed over smaller thumbnails. When you scroll over the small thumbnails it shows that picture above in the large thumbnail. Click on the large thubnail to get the full size picture. The only diference is that I want the full size pic to come up in its own window with a close button and a next and previous link depending on if there is a next or previous picture. Also if a user list pictures more than 6 allow for scrolling of the thumbnails. What I don't want is if a user ads ten pics and the small thumbnails are wider than the width of the large thumbnail above.
