The Gerber format that most manufacturers rely on today is vector. You might find one that can will work from a photograph, but it should be expensive.
You could easily DIY a 2-layer board from a photo, but then you face copyright. It's artwork, and in the US, a copyright exists upon its creation. It's more difficult to enforce when its not registered, but it can still be enforced. You could ask permission to make a specific number of copies, and that might be granted for a nominal fee, if you agree not to sell them. You aren't likely to be arrested for copyright infringement, but you could end up paying a significant civil penalty.
