Why not do both?
Sorry if this comes across as me picking on anything you are doing - you asked how it's working so I am commenting more freely with my thoughts here than I otherwise would have.
The picture shows the content without someone needing to click, but the link provides attribution for things where that matters more - like not memes but comics in particular, or artwork that people could purchase.
Here's an example where I recently did both: https://piefed.social/post/370988#comment_3945627. Do as you please ofc, I just offered in case it might help.
