), but I've been trying to change the directory of the images from the root of the gallery folder (as shown in the tutorial), into a separate "images" folder, so I've change one bit of the code that points to the directory (im not really sure if others need changing), and now, the thumbnails aren't showing(I haven't moved the thumbnails directory), but the links to the image files work.Here is my gallery page: http://animatorx.net/Minecraft/gallery/gallery.php

I've just started trying to learn php, but I can't find my probably obvious mistake 
(i didnt know whether to post this in the tutorial problems forum thing, or here, because this isnt really an issue with the tutorial code :s so sorry if its in the wrong place
)
, it works now! somehow I knew id missed something obvious, thanks
