For these posts, I’m typically scanning about 5-10 times as many thumbnails as I view at full size, then only downloading maybe 3/4 of those. I keep doing that until I have around 40-50 images, which I edit down to 20-25. Which means my leftovers folder has at least 15 images from each set, plus some from keywords that didn’t work out. In other words, ~250 pictures that are good enough to post but lacking a coherent theme. A chanpurū, if you will.
