Ok, without being too specific, we have various images, which need to be sent to various (public owned) mobile phones by way of MMS. The actual sending of the MMS is the easy bit, that's like 5 minutes work.

But it seems that there is no one-standard in terms of image size that can be enclosed in the MMS. Is anybody aware of a database which for a given mobile phone model can provide the maximum file size/resolution of an MMS image? Pay or free, doesn't matter.
