Photo Gadget Pro

Photo Gadget Pro is a shell extension that adds image editing options to Windows Explorer. It can rotate, resize, crop and rename images, add a caption and/or frame, apply different effects and filters (grayscale, invert colors, sepia, flip horizontal/vertical), carry out format conversions and upload directly to Flickr accounts. To use the program simply select images in Windows Explorer's window, right click the selection and choose an action from the context menu.

Supported image file formats are BMP, TIFF, PNG, PCX, TGA and JPG with four levels of compression. Crop function is rich with options so you can make a free rectangular selection, set fixed size crop area or use keep aspect option to constrain proportions while selecting crop area. When adding a caption you can choose between typing in text or using a graphics file. Framing is simple single or double outline where you set the width and colors. Multiple file rename mask is provided with several options including an automatic counter. If you have that kind of camera Photo Gadget Pro can also rotate images based on EXIF information.
