This works great and opens all imagesin the database when I open the url mywebsite/gallery.php, or I can choosecertain images (by category) by going to url''s likemywebsite/gallery.php?category=landscape Although the above worked perfectly with 15 images in the database, I''verealised that as I add more images to the database (I will probably have afew hundred images in total before long), I''m going to need to sort out thegallery pages so that instead of displaying, say, 100 images in a big longpage, it instead displays 12 images per page, and then has links to Next,Previous, First, Last, etc. After spending an hour going through Google searches, I''ve found some codewhich enables pagination from this website tutorial: http://www.tonymarston.co.uk/php-mysql/pagination.html I''ve inserted this code into my existing code, yet have came across a smallproblem. The pagination now works when I go to mywebsite/gallery.php andit''s great. However, when I go to mygallery/gallery.php?category=landscape,instead of showing the paginated Landscape gallery, it instead shows allimages from the database in paginated format, which is basically the same asthe mywebsite/gallery.php page In adding the above pagination code, I''ve somehow messed something up whenwanting to open galleries based on categories. I''ve copied the code below -can anyone see anything obvious I''ve done wrong? Through trial and error,I''ve tried to adjust the queries in the code, but to no avail.
