Artstor has some great art and design images, that may serve to inspire you.
- Britannica Image Quest
This is a huge image database, contained within it is the Getty Images Collection and content from the British Museum, and more. Well worth a look.
- Grove Art Online
Not as big as Britannica, and more focussed on art. More pictorial art than photography. Also has a reference section with definitions, a bit like an encyclopedia.
