Hm. I didn't realize you couldn't add vector art, the camera icon accepts the .svg type. But you can open the vector art with some other editor that will save it as .jpg; I've used Snagit to take a screenshot of a .svg and saved it as .jpg. Then you can add it by clicking the camera icon. Buttons you might be able to add as a code block, but code block is a recent capability above my pay grade.
