Hello Justin, You seem to misunderstand the working of the HTML <img> tag. All you're doing is to give an idea to the *browser* about where it should find the image, relatively to the *URI* of your script. Simply put, before you had: /cgi-bin/yourscript.cgi ---> img src="thefile.jpg" ---> browser tries to fetch /cgi-bin/thefile.jpg Now, you have: /ssiweb/yourscript.pl ----> img src="../graphics/thefile.jpg" ---> browser fetches /ssiweb/../graphics/thefile.jpg = /graphics/thefile.jpg You have almost found the best solution when in doubt: using absolute URIs. However, as you noticed, using the full URL is slower because the browser has to check the DNS again etc etc. So, if your graphics are acccessible as http://www.example.com/graphics/file.jpg, then you can insert an img tag with src="/graphics/file.jpg". Note the first slash which says to the browser "Begin at the root of this site and fetch the following URI". Ok? -- Per Einar Ellefsen [EMAIL PROTECTED]
