IllustrationFriday.com is a website that presents a weekly illustration challenge. A topic is posted every Friday and then participants have all week to come up with their own interpretation.
Topics are picked each week from a list of suggestions that have been submitted by participants.
To submit artwork it is important for an artist to have a website, most artists are using free services such as Blogger or DeviantART. Out of all the submissions one image is chosen randomly each week as the "Pick of the Week". Another valuable resource is the artists' forum, here you can read interviews and share ideas with others.
