I need to know how to use jpegs in a database.
I want the jpegs to be stored in a separate directory, so I need the table to know which jpeg to open based on the other information stored within the database.
In other words When I click on the navigators next button it opens up the relevant Jpeg and so on.
Thanks in advance.

Store the file name of the JPEG in the database table. When you move to a new record in the table with the navigator get the file name and load the JPEG image into an appropriate bitmap on the form.

If you want to store the JPEGs in the actual database table you can use BLOBs etc

Do it like this:

1. Place a TJPEGImage component on your form.
2. When you need to load an image (record changed...) do this

  var
    AStream : TFileStream;

.
  try
   AStream := TFileStream.Create(TheJPEGFileName, fmOpenRead);
   MyJPEGImage.LoadFromStream(AStream);
 finally
  AStream.Free;
end;

Cheers,

Raymond.
