if you stored photos there it would be a photoshed

huh, never made that connection. I guess because I'm not American. Thanks for clearing that up.

Just an FYI, outside of North America, the only shop specifically for work is a workshop. We would go to a auto workshop or a wood workshop. For Aussies or Brits a shop is equivalent to a store (often a small one). And yes go shopping at a shop or a store, you don't usual go storing at a store, unless it's like a grain store or a data store.
