Existing image comparisons still work, but new ones can’t be made and they can’t be edited anymore. Can you please check this?

We noticed that all image comparisons were replaced by the 2 images below each other, so there was no comparison functionality anymore. After disabling all other plugins and switching to a default theme, the issue remained the same. So I had to do a rollback to version 1.0.1 and everything worked again. Can you please check and fix this?

How to reproduce:

1. Install Image Comparison 1.0.1
2. Create a page or post with an Image Comparison block
3. View the post to verify it’s working
4. Update Image Comparison to 1.2.0
5. Refresh the page and see the issue

… error appears when autoptimize is used together with this plugin.
obviously something that has to be adressed.

Does this plugin have the option to select the images you want to compare? I’d like the ability to select images taken from different cameras to compare, complete with labels telling the viewer what cameras they are comparing.

Thank you!
