Where do you find image sizes for your content?

I'm working on code to query all of our organization's accounts and create a report to show total disk space usage for audio, video, and images. I can easily get the audio and video information by querying the web services and accessing the flavor assets for a media entry. But in doing this I've discovered the media entries which are of mediaType image do not appear to have any flavor assets defined. This seems odd to me because for the audio and video one of the flavor assets is the original file uploaded. I would expect to find a flavor asset for each image which reflects the original even though images do not need to be converted to another format. So what object in the API provides size information for images you upload into the KMC? Or is this not being capture and stored anywhere?

Thanks in advance,
Jack

P.S. It would be cool if you supported non web-browser image types like TIFF and BMP. You could provide a conversion feature to PNG, JPEG, and/or GIF for display on the web since you have the Flavor Assets feature for the other media types it should just fall into that structure without having to enhance the API.
