Hi Michel,

How about drawing one-pixel frame around any posted image by default. That can be accomplished with GDI+ objects or GDI+ API calls:

Step 1: load picture
GDI+ supports main graphics formats like JPEG, BMP, PNG ...

Step 2: draw one-pixel frame around it

Step 3: save modified image back to the file
actually it's going to be not exactly "save" but "create new file/release GDI+ object/delete old file/rename new file"

Take a look at this image:

It was created in those three steps in VFP plus GDI+ classes.
