Bad JPG rendered

Hello.

I'm using the QuickPDF library to render the first page of a PDF file to a JPG File. I developed the program and it works fine.

The problem is that it doesn't work so fine because in some computers the JPG rendered are in a very bad quality and it's not fully rendered.

Let me explain. It's the front page of a newspaper. If this frontpage have some photo in it, those photos will not render. Instead i will have some kind of "temp" files in the directory of my program (even if the PDF is not in the same directory).

Do you know why can be this happening?

Thanks a lot.

P.S: Sorry for my english, it's not my first language and I don't practice it a lot.

Ok. Library version was not the problem.

In my computer it renders perfectly, but in another computer not. Any idea?

Could this be a problem of a missing GDI+ library (gdiplus.dll)?  Can you look for this dll on your system and place a copy of it in the directory of your application (this way the application should use the local copy) on a machine where it doesn't render fine.
