The code portion of your ICF is limited believe it or not to 2MB at the moment. This according to what I've heard from Philips, this will be fixed at some later time to 6MB. You can check your code portion for size by temporarily changing you file extension to .zip. Check the size of the configxml in win zip. Adjust accordingly (delete stuff you'll need to do without).
I haven't actually run into problems with overall size as relates to graphics content.
