Hi,
unfortunately, this theme doesn’t include option to remove footer for one page only. This would be customization and we do not support customizations.
To set image in the footer you can use widgets.
In your Dashboard go to Appearance/Widgets. Depending where you want to set image (First Footer Widget, Second Footer Widget, Third Footer Widget or Fourth Footer Widget) you need to add thml code. In our theme demo in First Footer Widget we set Text and there is Lorem ipsum text. Below that text you can add image like this
<img src="smiley.gif" alt="Smiley face" height="42" width="42">
and image will be displayed.
Instead of smiley.gif (this is just example) when you upload your image through Media Library click on that image and copy link (look at attachment). Then change smiley.gif to your link and image in footer will be displayed.
Kind regards
