Image Body
The image body contains a standard jpeg file exclude file header. The actual size would be limited to (32K, 24K or
16K) minus header size (= 64Bytes). When the JPEG size is larger than the size of a target, the limit size is set up
small automatically. At this time, quality of image becomes bad rather than what was aimed at.
