Showing a JPEG stored in a BLOB

I must show JPEG images stored in BLOB fields.

To show a JPEG image, i use the TJPEGImage. But I can only make the
TJPEGImage show images stored in files. How to show images stored in blob
fields? (TDBImage only accepts BMP images stored in blobs, not JPEG.)

Any idea?

TIA

Look at Inprise/Borland's tech documents for an example

Take a look at the TDBJPEGImage I wrote, it does exactly what you need.
