I want to create a website that will allow viewers to color in the spaces of my modern-art, black and white drawings. What kind of software should I get? I want to be able to add a new drawing every day, and have an option for the viewer to print out their colored version. I have not created a website before, so I want something that is relatively easy and inexpensive, and that will transfer from my iMac to other Macs and PCs. Thanks!
