This is likely a naive and simple question, so apologies for that. I'm trying to incorporate figures in TeXworks. I understand I need to use the graphicx package. What I can't figure out is whether I need to install something before I put the \usepackage{graphicx} into the preamble.
If so, I have downloaded the .ins-file from CTAN and it's in the folder with all the other .tex docs, but not sure how to "activate" it from there.
Thank you

graphicx.styin your installation. It should already be there. – jon Aug 14 '16 at 02:02
