Custom Iconsets in Visio 2007 Pro

[DaBooch_Can]

Hey all!  Hoping to get some help with Custom Iconsets in Visio 2007.  I have read a few sites on how to create them but I am an extreme Newb WRT Visio and have been beating my head against a wall trying to figure it out.  Luckily, there appears to be an Iconset Builder that I see referenced a fair bit.  Problem is, I cannot find it anywhere.  Everything that has to do with the Iconset Builder and the Visio Toolbox points me to the Visio 2010 site.  I don't want Visio 2010.  Visio 2007 Pro is fine for me.  I just want to create a custom Iconset and the builder seemed the easiest.  I have 3 photos that I want as an option for the Iconset.  Can anyone tell me where the Iconset builder went?  Where is the Visio toolbox.  Thanks in advance!!!

UPDATE...... Seems like no one knows where to find this so I'll try another route.  I have 5 images.  How do I put them into an image strip for a data set in Visio 2007 Pro.  ANY help would be much appreciated.
