I cannot replicate this, but I suspect certain level Google Local Guides are being asked to upload specific photos to local businesses they are viewing. Here is a screen shot from Carrie Hill where she is being asked to upload a photo of food to this Starbucks local panel.

She posted the screen shot on Twitter:

I am not 100% sure if this is new. I have a feeling it has been around for several months but I am not 100% sure.

I know business owners can upload photos into different buckets relevant to their business type.
