For some reason my computer will not let me see some pictures on the net. The Computer will have a small box with a red X in the middle. Can anyone tell me why my computer is doing this?? Please help

Also, the webmaster can cause this to happen, accidently or by design. The only option you have then is to alert the site's webmaster of the problem, in case it is an error on their part and they aren't aware of it.
It could be a badly tagged page - Apache for example is case sensitive including in the file extension, so if the link is all lower case but the filename includes upper case, it fails to display. Ex, mypic.jpg, Mypic.jpg and mypic.JPG are not the same thing!
Are the images hosted by the site you are visiting? Ex, I won't allow my digital photography to be hot linked by pirates to stop the bandwidth I pay for being stolen by them, and to protect my legal copyright and ownership in my artistic property. So I use certain server-based techniques to cause the error you describe if anybody tries linking directly to my images from their site.

Knowing how to do that could be quite useful, can you give some advice?

Place everything inside sub-folders except the index page, then use HTACCESS and the robots.txt file to control access. This is effective in controlling what web crawlers do, what external links do, and in banning certain IP addresses (whole ranges if you wish), from any access to off-limit areas.
By using these within each sub-folder, you can vary the level of access to fit in with your wishes. The rules are not restricted to just images either, they work with any file type, which you set in the rule itself. The advantage of this method is that everything is a direct instruction to the hosting web server itself on what can be accessed and how it is delivered.
Other techniques, such as those javascript or DHTML codes, attempt to control how the user's browser behaves. That approach is flawed as it is client-dependent, so with the right tweaks and turning off certain protocols, 99.99% of it can be bypassed easily.
As an example I posted my Christmas web page in the Readers' Websites forum, but if you try that link now, it won't work. The page and content is still there, but I have blocked access until the season rolls around again.
