What’s the best way to make an image look new each time I post it on Twitter?

[Thea Keller]

I have a folder containing 100 images that I use for Twitter posts, and I rotate through them each time I post. However, I’ve noticed that the reach keeps decreasing. I’d like to know how to batch-remove the metadata from these images, or what else I can do to make Twitter perceive each one as a new image.
