Basically, I design book covers and logos for self-pubbers, and one of my clients wants me to turn her logo into a custom header. I don't know any of this coding I see here, I just want to know if there is a specific, optimized size at which I could create a header for her.
This is her site: http://www.jillinghoff.com/
Yes, I work in the erotica industry.
Thanks for your help in advance.
