See this posting:

The functions you should look into are:

jpeg_mem_dest(...)
jpeg_mem_src(...)

I have been using them for years.

Subject: [Libjpeg-devel-6x] read image from memory
 


I would like to save and read images from database. Is there any 
way how to decompress image without reading it from file stream or compress it without writing to the file stream? I mean I would like to work with it only 
in memory. The images should be in database and I don't see the sense of 
writing the images into separate files on disk because these would be huge 
numbers of files. There is one more reason for it. There is 250 bytes in the 
begin of file which are same for every image so I would like to remove these 
250 bytes and write them to db. So when reading data from db, I would complete the file in memory and then would like to be opened by 
libjpeg.
