kspeegle So, there is no way to add the "menu" to an "article detail page"? I thought for sure there would be a module position on the "article" pages I could just tell it to use that menu.
1) Have tried to replicate the same at my local install and as it is seen that It is module titled Portfolio menu being Articles - Categories type which is assigned for all pages being set at portfolio-menu position which is rendered in main-body component area however, it doesnt appear on article detail page probably due to some code inheritance set by default for template
If you will try to assign the specific module to footer position, It will appear on all pages including article detail page however the same would either require css tweaking to make it look nice or better yet, creating new module position at top position above or below main-content area to assign the specific module.
2) Try add this in custom.css file
.jamasthead.blend-bg{background-image: url(/images/joomlart/other/epcot.jpg) !important;}
Thereon, You can change your image and path accordingly as and when needed
