Not sure that I have clients who'd get the gist of something that non-pictorial. If it had a transparent bg so you could overlay it on a random image from http://www.randomimagegenerator.com/, would be more impressive since you'd get both the obvious dimensions and the aesthetics.
Plus, no uptime guarantee... that may seem nutso but I don't want a preview site to depend on the availability of an external site. Dev sez "until my server collapses"... not to be a downer, but I have enough worry about unavailable external services as it is! Maybe what is really needed is the same thing from client-side only, pulling the dimensions from img attributes and abs-pos a div w/the dimension text on top of a transparent GIF. If I were Ryan, I'd be writing that right now. :) -- Sandy
