Using icons without ox_inventory
When using ox_invenotry, the icons are set automatically. However if your server doesn't use ox_inventory you'll have to upload the icons manually. Here's how to do it:
Prepare your images (in a .png format)
Open pc_collections/html/img
Drop your images into this folder
Use refresh and restart pc_collections in your server console
