Lately I noticed a pattern on several answers on this website. People add images to their answers which do not add anything to them except working as an eyecatcher:
I really don't feel like downvoting these answers because otherwise they are perfectly on-topic and helpful. I edited the second answer to remove the image (which in fact the author literally described as "Possible rep-hoarding assistant" in the sourcecode), but the original author just edited it back in and I really don't feel like going into an edit war about this.
Should we have a policy regarding which kind of images are allowed in answers?
