Hi,
Thanks for using our plugins. I can try to help out here, but I am limited in supporting 3rd party coding.
The best I can do is provide css to hide the image on the single events in the header.
I am not sure how else the theme works so do not have anything else to hide it.
Try out this css:
.single-tribe_events #top-area {
display: none;
}
Add that css to your theme’s stylesheet or through a plugin such as Simple Custom CSS.
Let me know if that helps.
Thanks
