Back in July, 2003 shortly after becoming a Renderosity member I posted an image called 'Lonely' in the Vue Gallery. Someone has recently expressed an interest by email in using the image for a book cover. I have asked for further details and informed the person that a higher resolution would be preferable for print purposes. I have been offered $50 for the image. Perhaps someone with experience on using images for commercial images would kindly let me know if this the going rate for book cover images?
