This book describes the method of sending high Quality 2 Dimension,3 Dimension still and animated images over Short Message Service in GSM & Satellite Network. Presented method has two main blocks; first block converts images or animations into characters. And second block applies Huffman coding compression method on those characters and set them as a payload text of SMS. Generally, SMS is text based service and cannot send multimedia contents. For delivering multimedia contents, two other services are utilized which are; MMS (Multimedia Messaging Service) and EMS (Extended Messaging Service). EMS is an application level extension; can transfer predefined sounds, animations and images etc. But a drawback is that EMS is not supported as widely as SMS. On the other hand, MMS have richer contents than SMS and EMS. But for large files it needs higher network capability like 3G etc.
