link detection?
<p>I asked a question yesterday about a problem that Im having with a program that Im trying to build <a href="http://stackoverflow.com/questions/6331409/having-problems-passing-array-values">having problems passing array values </a>. </p>

<p>the problem that I am having is that I have an array named $images() that for some bizarre reason wont accept values, however last night as  was playing around with the program something very bizarre occurred.</p>

<p>one of the links actually worked, even though the array was still somehow empty? this has led me to wonder if the pages somehow have a way of detecting if the links are being processed and somehow disable link downloading perhaps? </p>

<p>obviously I cant confirm this, and is nothing more than a conspiracy at this point but is this even possible? thanks for your help guys!    </p>
