a configurable theme for podcast generator (currently supports v2.7) - http://www.podcastgenerator.net/
features an 'album art' style image, header image and background image options, and bootstrap styles courtesy of https://bootswatch.com/
install into 'themes\studio' folder
should work with the same requirements as PG needs. however, you may have to enable write access (for image uploads) to the directory at 'themes\studio\img.
activate the theme from the podcast generator admin page, a 'theme options' button will then appear in the menu/toolbar. choose a theme, activate the header and background as required and save! that's it!
