Card Layout(Background Image): Is there an option to have different background image for the welcome page?

is there a way to remove the image from all pages except welcome page?

Unfortunately this is not supported at the moment. I have now forwarded this as a feature request to our backend team. Please note that we can't give an ETA for when this will be implemented. Feature requests depend on the workloads of our developers and popularity among our users. But rest assured we will inform you once this feature becomes available.
