Calling a different logo img in album_pictureview

[maneri]

I have created a different logo just for pictures page and I would like this logo img to be called just in album_pictureview and socialgroups_picture. In order this to be achieved, I set up a condition and changed header template like this:

<div id="logo">
<a name="top" href="http://www.mysite.com/">
<img src="<vb:if condition="$show['picture_nav']">
http://www. mysite.com/images/styles/ALTERNATIVE-LOGO.png
<vb:else />
{vb:stylevar titleimage}</vb:if>" />
</a></div>


This condition works with an exeption, that is in case of album including just 1 pic (in this case picture_nav is not being used).

Any idea how to get this small mod in a different manner?

Thanks
