Is it possible to put a frame or border around a photo?
Not in Sandvox itself. Graphic Converter offers built-in frames and there are some specialised programs, too, such as Image Tricks (a lite version is available) and LightFrame.
It says "Avenger," but I am just a Sandvox user who has been assigned the title of Avenger here in order to be able to delete spam messages. http://davidneale.eu/
