What does the IrfanView lossless JPEG rotation plugin "optimization" actually do?
When I rotate a JPG digital photograph using the IrfanView "Options -> JPEG Lossless Operations" plugin, one of the options is to "Optimize JPG file".
The IrfanView 3.98 help doesn’t explain what it means to "Optimize the JPEG file".
Does anyone know what this "optimization" setting actually does? Should we leave it checked or unchecked?
