Sure thing, U must upload the picture you want to use as your deviantID and put it in that catagory, then all u have to do is go into edit your profile information and there should be something that says DeviantID. Click on the drop down menu and i should have a link to the image there to select. If ur still confused (cause I'm horrible at giving directions) u can message me again or look on the FAQ page here on deviantart for help k <3
