Need some help on products

Im not sure if this is in the right forum, Im new to this site. My question/problem is im looking for some type of camera or device that will let me take pictures and have them show up on my computer screen automaticaly instead of taking the memory card out and uploading the picture to the computer. I have a website that i sell live fish (www.aquascapeonline.com) and my problem is out of 20 pictures i take with the fish moving around, I am lucky to get one good picture. So i was hoping there is some type of system that will allow me to take the picture and automaticaly view it on the screen. Has anyone ever heard of anything that will do this. I really don't know much about photography so i would need some thing that is easy to use.

any help will be greatly appreciatedl

The software packaged with my Canon 300D enables me to control the camera from my computer. They call this function Remote Capture which also allows me to capture images directly to my PC without using a CF card and use the self timer or interval timer as well.

I was going to mention the Remote Capture as well. It comes with my Canon A70 as well. If you only want to use it for taking pictures of the fish to upload to a website you might want to look at the Canon A series cameras.
