It sounds to me like the JPeg graphic class/format is not registered.
Do you have the JPeg unit in your USES clause? Adding the JPeg unit to your uses clause will automatically register the graphic class. Try it. If it still doesn't work, let me know, I have a few other ideas...

Is there a way to do this using SaveToStrean/Loadfromstream instead of using Savetofile? The below does not work. I am trying to get a DBImage to display in an Image
Blobfield := fieldbyname('DeliveryPicture') as TBlobField;
blobfield.SaveToStream(ms);
Image4.Picture.Graphic.LoadFromStream(ms);
Blobfield := fieldbyname('DeliveryPicture') as TBlobField;
blobfield.SaveToStream(ms);
Image4.Picture.Graphic.LoadFromStream(ms);
