//Name: Simple Texture Changer (for inventory)(for one side or all sides).lsl
//Purpose: To "rotate" (change) the textures on a prim based on the textures in inventory.
//Technical Overview: The script finds how many textures there are in inventory, and uses a timer to change the
//                    texture on a side based on randomness or order. It takes into account inventory changes.
//Description: A simple textre changer script that changes the texture on a side(or all sides) of a prim to those in
//             inventory. It allows for a random order, or a logical "next up" order.
//Directions: Create a prim. Place pictures in prim inventory. Place script in prim inventory. Modify script parameters
//            to suit your needs. If you add pictures, and the script does not reset, manually reset the script.
 
//Compatible: Mono & LSL compatible
//Other items required: More than 1 texture in inventory.
//Notes: Uses a timer event. Should be low lag. Commented for easier following.
