How Do I Lock An Image To A Cell So That It Can Move With The Row/Column?

I'm currently working in Numbers and I am rather new to it. I'm used to the mechanics of Google Docs and Excel, but I'm finding that I'm not being able to accomplish what I'm wishing to get done. I am making a list, I suppose, that takes up a few columns each. It's a product list that states name, picture, price, and things of that sort. I am constantly adding to it, so I'm re-sorting it alphabetically quite often. The problem is that the images are not locking to the cell, so when I re-sort it, the image does not move with the row.

Any suggestions? I feel like I'm going crazy!
