Hello,
As First Aid is proprietary, we cannot provide those images. More information can be provided here: AnKing Step Deck Wiki
The HTML reference that you see on Ankihub is an empty URL pointer that allows, when media is present, for it to point to that card. This is unrelated to Ankihub being able to provide the actual media, however.
An example might be if you subscribe to Physeo and, in so doing, get their media package. Those HTML tags will then, upon having their media imported, point to the appropriate card and those images will populate. But for proprietary information, or anything that is copyrighted, we cannot host, or provide, the media.
Please let me know if that answers your question, and if there’s anything else I can help with.
