Saving logo images

I'm debugging the dropbox save function. I have the logo appearing on the DOM, but I don't have the jquery function that would save the image to dropbox working. I'm studying how the download logo feature works, and then learn how to apply that solution to download to dropbox instead. I'm also still wrestling with pixels on how the weblogo image controls appear on the create page. I'm surprised about how misalignment by a pixel or 2 really sticks in my side.
