Many times I have found that using the image from last volume of the series gives spoilers. I request the mods to add this point when anyone is uploading image for the series.

There's already a note in red tho? when you go to upload a new image

Still most of the titles have last volume image. Most of the time it becomes spoilery for me. Which Characters are alive or who ends up with who gets spoiled when I see the image and I get reluctant to pick it up. It will be great if we stick up with the image of first volume.
