I have a site with an image in the sidebar hosted on an external server. I change this image every so often on the external site, but the name of the file stays the same.
Recently, I've noticed that my site is not using the most recent version of the image. Looking at the source, instead of using the
example.com/foo.png I specified, it's now using
i0.wp.com/example.com/foo.png, which has a cache of an old version of foo.png.
Searching around for answers, I've come across many sites saying that Jetpack and Photon are the cause of this (for example, Why would image paths in wordpress suddenly change?). The solution for all of these seems to be to disable the Photon plugin.
The only problem is that I've never installed the Photon plugin, and any "how to disable plugins" tutorial I've found keeps pointing me to menu options I don't have, which I assume is because I don't have a premium account.
Is there a way to disable Photon as a non-premium user? (Or a way to at least prevent it from caching my external images?)
