impossible in php?

Hi there, I am trying to do something real dynamic. It looks like this is impossible in php because the parser would not work for the two cases. Following idea. - Create a dynamic image ( a card with a given text inside). I call it v-card.jpg and a .htaccess file takes care that the .jpg is parsed via php So the v-card.jpg is a php file outputting a jpg. This workes pretty good. - Create a pdf with lots of this v-cards inside. The function works with images from the filesystem, but not with the dynamic v-card.jpg image. Now I am wondering if this is possible in php, since both files are parsed in the same time. Maybe there is a work around or any hint you could give me. I am kind off stuck. Thanx in advance, Andy
