Yay thankyou! Hahaha, as for the description, I realized a lot of people weren't reading it and asking me questions that were already answered. So I was like, screw it I'mma be lazy, since the same descriptions are on my site anyway, lol.
Let me try to explain better. My sister is using JPEG images from various sources, which are limited to 72 pixels-per-inch and shrinking them down to fit the jewelry, using a standard 1200 DPI HP inkjet printer. The reason they don't look good small is because there simply aren't enough dots of resolution per inch in a JPEG. They would need to be about 300 PPI or more to look good that small. I've created some images in Paint Shop Pro that have 300 PPI when saved as (PSP) files. I believe that PhotoShop documents (PSD)can have up to 300 PPI as well, so it's just a matter of choosing better source material in her case. It sounds like you have a great camera to work with.
Oooh, I see. This one isn't a printed image, it's etched dichroic glass, so I thought you meant she was having a hard time with the camera. If she doesn't have photoshop maybe she could try .png files instead of .jpeg? Printers are frustrating, I'm not so good with them, either.
