 Transfering Image Files in COM Calls

I'm working on a criminal history system in which we have to transfer image
files from a database to a web page through middle tier objects. Could
anyone give me a general idea how this can be done. For instance, should I
look into serializing CBitmap or something along those line. I'm not sure
where to start.

Thanks, Ron

You should not use DDB, because it's device dependent. You may not want to
use BMP format either, because compression is not so good. Actually, there
is no compression for 24-bpp BMP files.

Consider using JPG or PNG file photos. Use GDI+ which handles lots of image
