rajivgonsalves Posted December 16, 2009 Share Posted December 16, 2009 well you'll have to keep the current position in mind so I guess its php+mysql, following will show you the third image $pos = 2; $result = mysql_query("SELECT * FROM photos WHERE photo_id='".$_GET['photo_id']."' limit $pos, 1"); Link to comment https://forums.phpfreaks.com/topic/185276-photo-prev-next/#findComment-978458 Share on other sites More sharing options...

rajivgonsalves Posted December 16, 2009 Share Posted December 16, 2009 it should have been infact, will show you the third photo in the category you might want to order it so you get correct results $pos = 2; $result = mysql_query("SELECT * FROM photos WHERE photo_catid='13' limit $pos, 1"); Link to comment https://forums.phpfreaks.com/topic/185276-photo-prev-next/#findComment-978475 Share on other sites More sharing options...
