Narinder, Thanks for asking that question.
CONVERT PICTURE($Photo_g;".jpg") PICTURE TO BLOB($Photo_g;$Pict_x;".jpg") BLOB TO PICTURE($Pict_x;$Pict_JPG_g) The new, converted picture size is a couple hundred octets, no longer 244 Ko’s. It appears either as an entire transparent background or a blank picture. Paint.net saves a JPG in 34 KB form 244 KB. I suspect the PNG is compressed somehow and not correctly convertible.

I wonder if the issue is with the parameters that you are passing to the CREATE THUMBNAIL command? But then again, I am sure you must have double and triple checked that...
