   There is also another reason to store as JPEG: The very same database is the   
   source to some web-pages, and in that aspect there is a concern for speed an   
   performance. With a high quality JPEG compression, there is very little   
   degrading of the images. My hope was there could be integrated a third-party   
   s/w for this into Paradox.   
      
   You may have some points in storing graphics outside the database, and only   
   storing the path. However, there are also some drawbacks doing this. Reports   
   in Paradox draw images directly from the tables in a very nice way. With the   
   files stored outside the database there will be a problem doing this. The   
   same goes for showing images in a table grid on a form, I do not know how   
   this can be obtained without the images beeing in a Paradox table.
