[boost] [quickbook] Where to put my pictures?

Hi Everyone, How do I put images into QuickBook documentation? The manual says I should put: [$images/img.png] But in which location am I supposed to put the picture? Currently my documentation works if I put folder "images" with my PNG image inside folder "html". But the latter folder ("html") is generated by b2: it would not be there if I haven't run b2. Assuming I only want to keep QBK sources, but no generated files, where do I put my images, so that b2 works? Regards, &rzej
