Pandora Image Viewer (PIV) by Jon Sneyers is a simple and fast image viewer.

Features:

– Camera raw formats now supported using exiv2 preview extraction for fast viewing and UFRaw for conversion
– Improved crop: multiple crops per image (“N” for new/next crop, “P” for previous crop), crop using touchscreen (much easier!), overwrite originals with backup OR crop to new files
– Better behavior when called from file manager
– Configuration (piv.conf in appdata or .piv.conf in image directory)
– Fit width (“W”) or height (“E”)
– Comic viewer mode: put a file called “.comic” in an image directory, and PIV will use different settings: no editing, fit-width, remember last viewed file
