Hi Moshe;
I do that all the time in PB using either the InkEdit or InkPicture control as these render TIFF images just great! 
You can also use the these control equivalents in the DataWindow as well. The bonus here is the ability to be able to "Zoom" the images in/out using the DW's zoom support. 
Finally, if you are on PB 12.5 or higher you can use the new TABLEBLOB feature in the DW to negate the need to use any SelectBlob or UpdateBlob commands any more. 
HTH
FYI: here is a snap shot from my PB 12.5 IDE of a TIFF image being displayed and its "thumb nail" from right inside the DW painter.
Regards .... Chris
Note: I am referring to PB Classic here BTW.
PS: when you want to deploy your PB application as either a Web or Mobile application - you can use this technique for TIFF images when you add the Appeon product to your PB environment!
