PHP in Opera browser and TTF issues.

Hi guys. I need a little help. I had made a small PHP script to generate a .jpeg dinamically. In IE it works great, but when I try to get the same Web page from an Opera browser, I get the Image box but not image at all. By the other side, when I get the .jpeg in the IE and I try to print it or save it, some text written in arial.ttf (the one that comes with Windows) is not printed, not saved. Any idea of this two little problems? Thank in advance. gustavo.-
