PhotoFlare
Description This is an effort to bring quick, simple but powerful image editing to the masses. PhotoFlare is inspired by the image editor currently only available on Microsoft Windows – PhotoFiltre. However, it will not be a straight clone. It is being built from the ground up to be much improved and cross platform too! Features: Easy quick cropping tool. Flip, Rotate and scale images. Lots of unique image filters. Batch processing tool with support for all editor features. Multiple translations are supported.
