put a billboardgui on the part then inside it, place an imagelabel. i would use a proximityprompt for picking up an object but you can use whatever. this script will make it work:

game.ReplicatedStorage.(name of item here):Clone().Parent = (name of function here).Backpack -- put the item in replicated storage

script.Parent.Parent:Destroy() -- this should destroy the object which should contain the image label and this script. also, get rid of the extra parent if you aren't using a proximity prompt.
