Could anyone do this? All it would need to do would be gather item img urls from neo to filter and put them into a .txt file. It could probably done pretty easily by someone who knows PHP or Java.
That would actually be pretty easy: http://items.jellyneo.net/index.php?go= ... 75&p1=&p2= Search JellyNeo, and grab all the links that don't contain the specified items in a listbox.
Why would you get a list of every item when you could just add 1 filter? Code (Text): http://images.neopets.com/items/*.gif :O Magic.
Wouldn't a better program be to get all the items from a shop (save-able to a folder) then, remove a specified list of items. Like ABing lists could work for this
