I just had a quick look at how album art on a per-track basis reaches tuners. In the US, analog FM radio gets it through a side-channel… a separate signal called HD radio.
And apparently DAB+ incorporates album art into the signal. This seems to be the difference between DAB and DAB+. I guess the question is, does the HD radio side channel approach ever happen with DAB (non-plus)?

Plain DAB and DAB+ are identical - DAB+ just uses AAC instead of MP2. So whatever works on DAB+ will on DAB too.
I’ve never seen album art on any station, although I’m aware there is a slideshow (I’m not sure if that’s the correct name) feature for images. I’ve not seen it used.
