If you are trying to convert old PICT formatted imaged in 4D Write areas — which it appears you are trying to do — you will need QuickTime installed on your machine so that it can read the PICT format and put the picture into the BLOB. Use PICTURE CODEC LIST to see if your machine has QuickTime installed and thus available for use. https://doc.4d.com/4Dv17/4D/17.1/PICTURE-CODEC-LIST.301-4179097.en.html You may also have to reactivate QuickTime support with SET DATABASE PARAMETER(QuickTime support;… to get it working. https://doc.4d.com/4Dv17/4D/17.1/Pictures.300-4179081.en.html Tim ***************************************** Tim Nevels Innovative Solutions 785-749-3444 timnev...@mac.com ***************************************** ********************************************************************** 4D Internet Users Group (4D iNUG) Archive: http://lists.4d.com/archives.html Options: https://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4d_tech-unsubscr...@lists.4d.com **********************************************************************
