IrfanView is a wonderful freeware Windows swiss-army-knife for image viewing & editing.
For me, the key features are fast viewing, simple editing (crop, contrast, brigthness, rotation, resampling), file operations (delete, copy to folder) and extended image information access (exif data) combined in the same interface. Versatile batch jobs are a very nice bonus.
But unfortunately IrfanView is for Windows only, and isn't free software. What would be the nearest equivalent for linux?
