Adding image behind item titles on product details page

I would like to know where I may add a background image for my item titles on the product details page. I already know the code on how to do it. I just need to know where in the stylesheet I can add it.

Example:
https://www.schobookcollectibles.com//index.php?main_page=product_info&cPath=65_68_73&products_id=319

I would like to add a image behind the title "Cell WA-018 Rare". Just like with the side-boxes titles.

Thank you,

Product titles are wrapped in an H1 with an id "productName", so either edit that id in your stylesheet, or create product_info.css and add it there.

Thanks. The image does not seem to work for some reason, worked with other things but not this, so I used a border instead.

Thank you for you help.

Check your config files, your base href has an extra '/' (so everything is .com//index.php) - the config examples that are in the zen-cart docs folder explain when to leave a trailing slash.
Also, your template name is "custom template" - I do not believe it's best practice to use spaces in folder names.

Yes about the double slash. I had contacted blue host about it but they did not do anything about it. I pretty much came up like that even before I went to edit my files. Thanks for the advise I edited public_html/includes/configure.php and it worked. Finally no more double slashes. Thanks a bunch!
