Like I said....right-clicking the picture and selecting properties will pretty much tell you the problem.If it's just"http://",then there is no picture on the site.It hasn't been uploaded.If there is a full url like "http://www.pctech.com/logo.gif", then there is a picture but it isn't loading properly.Sometimes refreshing the page will bring them up.It's 9 out of 10 times not your pc but the website your on.
Most webmasters don't leave blank pictures...
