Im a photogrpaher for
London Fashion show and have had an
exhibition in Tate britain October 2008, and trust me camera price has NOTHING to do with it.
Im not name dropping BTW, i am just showing that this is what i do for a living.
An expensive camera is only pushed by salesmen at Jessops telling you what you NEED and have to have. In the same way as PCs are pushed by salesmen at PC World. If all you do is browse the internet and use MSN Messenger, an old recycled Pentium 4 will be more than you need, but they still push for some quad core system wih about 8GB of ram, something in comparison to what Nasa will use to launch a rocket.
Even if you bought the second best 35mm camera you can get, the "Canon 5D mk2" for £2400, You will have almost the largest sensor, the best options and incredible image resolution, but your then still going to reduce down the images to 800 x 600 pixels or so to fit on your website.
if your using it only to make web images, get onto
ebay and find a good second hand Canon SLR like the 10D or 20D camera with the standard 18-55mm lens. They are dirt cheep and 3 - 7 yrs ago were counted as professional, so if the images were good enough then, why will they not be a few years later???
(Note - SLR is the type of camera where you can chnage the lens on the front)
I wouldnt pay anymore than £150-£200 for one, as a new Canon 1000D (The most recent entry level canon SLR camera) is only about £399.

But...
The main bit of photography that makes things look good is lighting, there are loads of home kits to help with this.
Lighting
Light Tent
Jewelery Photography
These are a little expensive, mainly because i just spent 3 mins looking, but if you read through the text in the adverts it will give you a good idea of how it all works and what to look for.
But honestly, you could take the images with a simple compact camera, its the lighting that makes all the difference. Just make sure the camera has full controls such as manual shutter speed and aperture, as auto settings are for idiots and usually dont give the best results.
So for about £50 - £150 for a new compact camera or second hand SLR and £100 for lighting, you will have a semi pro setup.
Hope this helps
