I have taken some photos(.jpg format) from my digital camera Sony DSC W-170. The image opens in Microsoft Photo Editor and Picture and Fax viewer in my home computer. The jpg image does not open in my office computer. I have installed the camera driver and software in my office computer, but still the image does not open. The thumbnail image is also not displayed. When I select Edit I get error message ""Paint cannot read this file. This is not a valid bitmap or its format is not currently supported."
