Thanks! I just tried Omnivore, but it appears that highlighted images are broken in Obsidian; these images don't link to the original image but rather through Omnivore's own proxy, which (for me) breaks the images.
I prefer the Pocket > Readwise > Obsidian route, meaning I use the Readwise plugin in Obsidian. It costs a pretty penny but doesn't send images through a proxy...
