I am not new to WordPress but am new to customising a theme. I am currently using the Chaoticsoul theme and would like the header image (or banner) to just appear on the home page. Currently, this image displays on every page created. I have read that the header.php file (whenever that is located) needs to be edited and I have read that I have to edit my CSS file. any help would be appreciated.
The blog I need help with is optiqueiowa.wordpress.com.
