The best watermark plugin for WordPress

I’m looking for a decent watermarking plugin for images on WordPress. I have come across a few, as well as forum posts, but the most ideal of which would be ones that actually add the watermark on upload.

The only one that I found that can do such a thing is Marekki’s Watermark, which is significantly outdated (plus, it crashed when I tried it last time anyway).

I found one that works similar to 9gag’s watermarking, adding it to the bottom of the image, but it is a little concerning when it recommends backing up the entire mysql table as well as all the images as if something can catastrophically go wrong.

TL;DR: Looking for the best watermarking plugin for wordpress images, and hoping someone has experience/opinions on one for the best use
