Thanks RH.
Total Commander is the single app I couldn't live without. Batch renames, ftp access, file compression - all built in.
FireFox users can find free Add-ons like 'Screengrab'.
I use IrFanview, hit 'B' for batch mode and can resize, sharpen, etc I've never used it for scanning with.
Can't say I've heard of JPEG Optimizer before this.
