I'm trying to save a JPEG image in Delphi 3.0 to an Oracle LONG RAW
column.  Currently, I do the following:
1. Acquire an image from a digital camera into a TPicture object (using
EnhTWAIN)
2. Use Delphi's JPEG unit to convert the TPicture to a JPEG
3. Assign the JPEG to the Picture property of a TDBImage control
4. Post to the database

I guess TDBImage.Picture does not support JPEGs, so my image does not
display in the TDBImage control, and nothing is saved to the database.
If I assign the original picture to the TDBImage, it is displayed and
saved to the database, but the file is ~10 times bigger than the JPEG
image would be.  The original image is around 5MB, and the JPEG image is
around 500K.  I will need to store hundreds of such images in the
database, so compression is a MUST.  Can anyone provide any pointers as
to how I might accomplish this?

The process is flexible, but the compressed image MUST be a JPEG.
Thanks for any assistance you can provide.

I am using Delphi 1 so I had to aquire a third party component to use
JPEG images.  It supports the use of streams, so I can use a TBlobStream
component to read from and write to the table (a graphic field in a
paradox table).

I haven't fully tested all of this yet - that will be tomorrow - but if
it doesn't work I will try using a bytes field (which as far as I can
tell is simply raw storage of data).

I got the JPEG component from the Delphi Super Page, in case your
wondering.  It shouldn't matter, though as I am fairly sure that the
Delphi JPEG components (whatever they may be) support streams.

If anyone's in Cape Town, South Africa and keen to give me some tutoring in
Delphi (about 2 hours a week) please drop me a note.
