zenvision

Hi everyone,

i have a problem. I embedded the gallery as iframe into my website. When i click on a photoalbum and then on the thumbnail the window is too large. And i dont wanna make the images smaller. Is it possible to open a new window when i click on the thumbnail like this http://minishowcase.net/demo/ this is also with css, java and ajax possible. Or what can i also do? My iframe size is width="750" height="500" with default theme. Zenphoto is an awesome gallery i hope someone can help me.
