Ok, well it may be that your internet cache is full (the folder where all the pages you've looked at on the internet are temporarily stored on your computer) as this can slow down sites and stop photos being displayed. Not sure which version of IE you are using but if it's IE6, click on Tools (at the top of the page), then click Internet Options, then in the Temporary Internet Files section on the General tab, click Delete files. This should clear out your cache and hopefully allow you to see photos etc. If this doesn't work, there are a few other things you could try, as listed
