<blockquote><i>When you use $$img{...}, what does using two $'s mean...does that signify that you are using an array of hashes rather than just a simple array
</i></blockquote>
Yes and no. An array of hashes are really an array of references to hashes. Therefore when you fetch something from the array, you get a hash reference back.<br>
To actually use the hash, you then have to de-reference it. There are two syntactic ways of doing that <code>$reference->{} or $$reference{}</code><br>
I like the latter best, mostly because its shorter and because it is coloured yellow in emacs...<br>
