Avoiding caching problems

The following process has worked for me. Do you have any comments on it.

I had a file on my computer image1.svg and loaded it into WordPress media. I wanted to change the image so I:

. created a new file image2.svg

. opened WP media to view image1

. replaced image1 with the new image2

. used the option “Replace the file, use new file name, and update all links”

. reloaded caption, description etc.

. I immediately saw the impact of my change on each webpage that displayed the image.

. I did not have to purge any caches

I had caching problems when I:

. updated image1 by overwriting my file image1

. opened WordPress media to view image1

. replaced image1 with the new image1

. Used “Just replace the file”

. the cache kept on showing me the outdated version of image1.
