FrameFun is a simple software to add frames to Bitmap, JPEG or PNG images. You may select an outer frame, a border around the image and a drop shadow for a 3D effect.
You can modify the color and width of each Frame, Border and Shadow. You may additionally modify the direction of the drop shadow.
A Batch Conversion option allows you to "frame" several pictures in one go. If the pictures have different sizes, you can select a relative Frame/Border/Shadow width.
FrameFun allows you to add subtle frame effects with optional drop shadows and colored background to your images. You can also add a plain or oval vignette effect and optionally batch process an entire directory. You can play with the settings and adjust the frame and drop shadow, use just a frame or vignette etc.
