* IrfanView Shell Extension *
This PlugIn shows a Context menu for some IrfanView (4.38 and later)
operations in Windows Explorer, Total Commander or other file managers.
You can select several (picture) files and perform IrfanView operations:
- Play slideshow with selected files (using current IrfanView slideshow dialog settings)
- Open selected files in IrfanView Thumbnails window
- JPG Lossless Rotation (automatic rotation, based on EXIF orientation, optimize ON, keep all markers ON)
- Convert pictures/images to another format (same folder, copies will be created if the result file already exists)
Thanks to Michael Dunn!
