Singing the Gallery Submission Blues

I'm having a little trouble getting my widget past the gallery submission approvals gestapo and as a non-techie I can use your help everyone. The first time I tried submitting it was rejected as the size of the widget didn't match, so I clicked "dynamically size" in the Edit widget page and after submitting again, I get back "Your widget's content is either empty or failing to load. Please ensure that your widget looks as you expect it to on the widget's Dashboard and resubmit your widget for approval into the gallery." My widget loads fine for me in the Preview section of edit widget - in both IE and FFox. It is a little slow to load, because the images are loading from a web 2.0 filestore that authenticates first (and I have no control over this, it is the only webhost I have), but eventually it loads perfectly and I can it where I have it subscribed to. Should I try resubmitting for gallery approval as is with no change, or any layman-step-by step recommendations as how to change things are appreciated (ie tweak to the html code, or way on widgetbox to build the widget as flash instead of javascript etc), or otherwise. Many thanks!
