I've just gotten started with DoodleKit and have had no issues creating pages, linking to my domain name, etc. But I cannot upload any pictures.

In the upload dialog I click "choose picture", pick a picture and click on it. At this point the progress indicator just spins and spins and never loads the picture. This is a small jpeg I'm trying to load so it should be nearly instantaneous.

I work from a Mac using Safari. I've had no other issues working with the tool so far. Any thoughts?
