CyberChimps is a WordPress and Graphic Design asset store. I’ve been using them since 2010-ish for all my WP themes. They were one of the first companies to focus on responsive themes.
Philip M. Hofer, http://frumph.net/, created a brillant plugin and an amazing webcomic package for WordPress called ComicPress. I guess you could call it the standard installation for webcomics.
I, however, wanted to use my own themes. Thankfully Mr. Hofer created a variation of his product called Comic Easel (https://wordpress.org/plugins/comic-easel/). So… I used Comic Easel and the themes I’ve bought to create my own sites.
Recently, I purchased a membership with CyberChimps for access to all their themes. My intention is to modify these reponsive themes to create webcomic sites which work on mobile devices.
