popup domination plugin calling over 350 kb obsolete files

I have been using the popup domination plugin for quite some time now.
It works nice, but creates a huge load on the server every time its called.

At first I thought this might be normal, until I figured that the plugin is calling all possible image files it got for the different templates every time you use it.
E.g. You select the “blue template” it will show up properly, but it will load all other color.png files as well – even without using it.

Here the list of over 30 files popupdomination calls every time its displayed, creating over 352 kb of load on every page call.

Total kb files called by popupdomination plugin 352,3

As you can see, it loads all different color png files every time its called, causing an unnecessary load on server and bandwith – not to mention page-load speed.

You can check this for your site (if you have popupdomination in use) by using e.g. http://tools.pingdom.com/fpt/ to see how this delays your page.

Is there anybody out there who knows how to fix the plugin, so it does not cause this server load every time?
Would be great to hear from the creators.
