francesco,

justpath(dbf('commel'))+'\schemi\' + iif(empty(wcml_commel.schema),'vuoto.jpg',alltrim(wcml_commel.schema))

here is the code I use in a report and it works. I also tried it in VFP9,

I gave a glance to the image property and I have this situation in the general page :

ControSource type is set to variable name
i haven' tried the other option Yet

Ciao
Alessio
