Hi Luis;

  Neither the DataWindow Control or DataStore support the SetPicture() method.

  So for DWO pictures, you would have to use the "Display as Picture" property. This means that if you're storing the images in the DBMS as "blobs", then you would have to perform a SelectBlob command followed by a FileWrite() command to save the image to the App's image(s) working location. Then set the "Display as Picture" property ON and the value of the column / compute / etc to the name of the Image File you saved it as.

HTH

Regards ... Chris

you can also use bitmap() in a compute to display a picture

bitmap( 'filename' )

and its just like display as picture in that the file must be saved to disk.

Another good alternative Mike!

FWIW: The only issues that I came across using the Bitmap() method were: a) certain image types are *not* supported and b) the converted image can be a bit blurry (depending on the original image's size & type).
