What is the best way of dealing with large JPEGS?

What I would do (and is what I do) is this. When you have opened your jpeg after scanning, immediately save it as a TIFF, but first resize to 300ppi and a manageable file size, say 3600 pixels long edge. This should give you a file size of about 49.5 mb. Save it as a 16 bit TIFF, scrap your jpeg copy and use the tiff as your non-lossy working file. You can then work on the 16 bit file without deterioration and resize and save as jpegs at either 72ppi for the web, or sized for printing to suit at 250 or 300ppi accordingly. When saving as jpegs from TIFF you will have to change the image to 8 bit. Providing you save your spin-off files in another location, your TIFF file will remain a virgin master. What I have described above is simple to do in Photoshop CS2, which is my present edit programme. You will have to sort it out in whatever programme you are using, but I'm sure it won't be difficult and in fact will be much the same as I do.
EDIT: Give your TIFF masters a working title and keep them in a separate folder. Like wise your web files. I keep a separate folder also for my TIFF 'portfolio' files from which I make all my print files from when needed and also create my low res flickr images from them.
