I have a Lenovo 3000 desktop using Vista Business. I scan my images at 600dpi (irrelevant, I know) on a Canoscan 8800F using Nero then change the resolution using Photoshop Elements 5.
err, in this case I don't think dpi is that irrelevant.
I know how people can get confused, Adobe especially can be confusing, when they mention DPI but actually mean PPI.
Try changing the "size" of your pic with the "resample image" box un-ticked, if you are resizing down ... check the box if resizing up. Ignore the resolution pixel/inch for now.
PPI (Pixels per Inch) and
DPI (Dots per Inch) are frequently used interchangeably in the industry, by pros and amateurs alike. While wrong, this isn't a huge problem since we usually know what we're talking about. To be absolutely correct it's worth noting that scanners, digital cameras and screens are all measured in PPI while printers are measured in DPI. Just so you know the difference.
