Yes the printer also makes a huge difference - some of the thermal wax printers were only about 300dpi but becuase of the bleeding/blurring they gave much nicer images than 1600dpi inkjets.

I agree. My first Olympus was a 2mp and it is mostly OK at A4 size but on some details images you do notice pixelation. I moved on to a compact 4mp which though higher resolution is actually not really any better in terms of image quality, so earlier in the year I got a 9mp Fuji 9500 and that is brilliant because you can crop loads out of the picture and still end up with a 2-4mp image

Yes but his images are 2 megaPIXELS not 2 megaBYTES

9 megapixel image from my Fuji is about 2.2MB in normal mode and 4.5 in high quality JPG mode so a 2MB file must be quite a high res image

OK you are spot on. I need to go and see my Optition again, or so he keeps telling me.

Don't think I've ever shot 2Mp. My 5Mp enlarges to 16x20 with no degradation. Don't recall going larger.

Large images are typically meant to be viewed from a distance. You my get away with a less-than-photographic-quality image. Pick a quarter of your image and print it at the size you want, and see what happens.

If you do much image manipulation, you should open the jpg, edit, save in a lossless format, re-open and edit, etc. and then, if desired, save the final back to jpg. Jpg images lose information every time they're saved (nature of the beast.) The fewer jpg saves the better.

Agreed. Remember that 'pooter screens are typically 72 dpi resolution. Inkjet printers are consderably finer resolution. I don't imagine your camera can shoot RAW images, but if so, then do so. Thee contain the greatest amount of data. Jpegs are compressed files and the image suffers accordingly....

The best thing to do is try it and experiment. The nice thing with a poster is that one looks at them from a distance, so they are perhaps a titch more forgiving...
