windows 2000 act up!!!

Can somebody please tell me how i can enable the image preview in my folders? You know...after you enable web content in your folders, and if you single click on a jpeg,gif or bmp file, the attributes and the picture gets shown on the left side of the window. It was working fine like this untill i installed office 2000 with microsoft photoshop editor. After that when ever i single click on any image file, only the attributes gets shown but not the picture. To do that i have to go to customize folders and enable image preview which then creates a huge ugly box on the bottom left corner of the window like how it is in the "my pictures" folder. I want it to be like how it was previously before i installed office2000. I want it to generate the preview when i click on any image file without having to enable that huge image preview box at the bottom left of the screen

try going to folder options and enabling web content

I tried that but it doesn't work.
Do i have to do anything in the registry?
Like do i have to change anything in the H_KEY_LOCAL settings?
Please help!!!
