This highlights where THT went astray with the subscription update. (Please, everyone, restrain yourself from saying "They need to make money!" That's not being questioned.)
Many of the target users ("Made for ages 9 - 11", App Store) either don't understand the concept of Copyright or won't respect it. Additionally, I believe allowing the import of external images strays from the core objectives of the application - promoting coding, and by extension, creativity for a young target user base.
IMHO an app targeted to ages 9-11 should not encourage them to go find any picture they want on the Internet. I would have designed subscription service to enable a module within Hopscotch for drawing custom Characters/objects (which should be limited to a certain pixel count). Furthermore, the subscription would have added new object called Background (since custom Characters/objects would have been limited in size). This Background object would have a special When event called Before Game Starts. In this event you'd code backgrounds the same way you always have with one important exception. The code would execute in advance (perhaps on the server) and be saved as an image with the project so it's displayed without lag. Export of external images would no be allowed. That subscription service concept stays true to the idea of promoting coding & creativity. It retains the constrained environment and is something I would pay for for my children, ages 5 & 9.
