How do I remove course image from the new theme section

I have posted already extensively my opinion of the priority of releasing this feature before many others i can think of... However, i welcome this feature in the following scenarios:

For companies, using internally and externally one brand.
This is a first step towards possibly? having global ( branding one for all in the team ) branding controlled from one place., from the admin, as it should in this scenario. Developers in the team should not have the option to mess with branding. Or even have to be concerned about it, at least not from the system look and feel point of view, Uploaded content is another matter. They still need to learn/consult the branding book.

As developer with various customers - provided that the team leader (main admin) can assign rights to turn of the global branding setting in any new courses..and dont effect existing courses in doing so..
Then i think, again, the themes feature does have the humble beginnings of what can become  some good and interesting options for course look and feel differentiation.

I have read the comments and i expected this when seeing the feature and how it was implemented. I happened to see it very early i think. The "whats new page" had no info on this when i checked it for descriptions of the feature. 

But true to Articulate tradition i have seen so far, they do listen and will gradually improve. This time it might be more urgent for some user scenarios, but still, in a few months time and hopefully some updates along the way, the themes feature will be a natural part of the new rise experience. Overall a good thing.

Also i wanted to share the video provided  - internally in the companies E-learning developer forum, but i could not figure out how to get the link the video. Maybe the link can be posted by support for sharing?
