I created one in powerpoint and then hit print screen and pasted it into a word document - does anyone know how to save the image from there as a jpeg?
I use Big Huge Labs Mosaic Maker (compatible with Flickr) to create inspiration boards. http://bighugelabs.com/ Here's mine:
You can now create inspiration boards right on PW. Click on Tools > Inspiration Board
You can upload pictures to assemble your mosaic.
