No problem, you can also consider converting the PDF to a jpg and posting that. There is an online program to help with the conversion. I have done this before.
http://pdf2jpg.net/Is one site to do the conversion.
You could also make a screenshot of the PDF.
Like most stuff in our digital world, there are several ways to accomplish the same thing, you just need to find the one that works the best for you.
Good luck...
