Hello Everyone,

I apologize in advance if this topic has been covered, but the search function has never worked for me on this forum.

Anyways, I just spent two-years writing a rock guitar method for kids, and I am in the process of uploading the pdf to Create Space for publication, but I'm receiving warnings from Create Space about the resolution of the image. Essentially, the resolution is lower than 300 dpi, and I would like to fix the problem as the book is full of diagrams created with this program.

Can anyone help?

Thanks in advance for all the great tips.
