Some web designers are lazy and use the name of a file as a alt description too. This is why Voice Over reads out these images as .gif .jpg etc even when navigating by image with description is set. My advice is to email the webmaster of the offending website and let them know that the alt descriptions on their site are not useful and if the image is there for purely decorative reasons then the alt tag should be left empty i.e. alt+=""
I must admit though I do find it annoying that VO reads out vertical line, it is a shame we can't get VO to ignore this character whilst reading HTML pages.
