Since many of us are now writing here on Steemit, I started a new thread on cryptocointalk and uploaded all ads, images and banners I have created so far for our various advertising campaigns. That way, everybody can use them for enhancing our articles here on Steemit.

We should probably have something like a central repository for such stuff, otherwise all those images (like for example splash contest images) get scattered and buried in various threads and it will be hard for future newbies to find them and use them.
