merry marigolds

Tagetes as I know very well that delight our autumn garden for sure.Gregory,I have a question about a sign on our photos,what does it means ''impressions'' and number we see there?

Thanks Radu- I found that also curious- by putting the cursor over the "impressions" it says it means how many times the photo has appeared in a list as a thumbnail, or was directly viewed- so, maybe when someone scrolls through like the "critique" section and the photo is there? Not really sure. Another mystery of PN :)- if anyone else has a better idea, let us know!
