Well, if I upload their photo it’s stealing so won’t do that. But I don’t think that’s what you’re suggesting. Just generalities. At the link there is a little slideshow that shows a couple of the cupcakes.
But you aren’t costing them money if you upload it to your own server. You also wouldn’t be making money off it. What you were doing was stealing, too, just a different type and it cost them money which is why they find ways to prevent people from doing that.
