While using FlowRouter if I load my page any locally served images (images/myImage.png) works fine. But if I navigate to a page and then navigate back (home page -> about page -> home page) the image is broken. However in the developer console, if I hover over the image source, the image appears fine.
This is not an issue with images served from another server.
So if you use params in your url (not queryParams) this can break images if you do not clear the params. However this has not solved my issue, I want to make sure it was noted for anyone else who comes across this.
