Mona, You have to provide closeup pictures of the bottom (inside the foot rim), the foot rim itself (partial is fine), and the inside of the bowl. Are there traces of gilt decoration? Photograph it too.
Can you upload these pictures them somehwere on the web (e.g. Flickr, Photobucket, etc.) and post or send the link? Sorry, but, as long as it is standard items small pictures might do, but normally details, including blemishes, age signs, etc. should be visible. The high foot of your bowl is a bit unusual for such items.
