The anchor tag in there does not have to come before the iframe. It can be coded after the iframe if that code makes more sense when you look at it.
<iframe style="position:absolute;top:50px;left:50px;width: 500px;height:500px;" src=https://imlive.com/hostlist.ashx?cat=1&Roomid=10,160&fromsearch=detai l&gallery=1&captionid=1 scrolling=no></iframe>
<!-- destination url -->
<a target=_blank href=https://imlive.com/hostlist.ashx?cat=1&Roomid=10,160&fromsearch=detai l&gallery=1&captionid=1>
<!-- This div overlays the iframe -->
<div style="position:absolute;top:50px;left:50px;width: 500px;height:500px;"></div>
</a>
That works the same as the other code I believe.
Anyway, I hope that helps with the situation.
