Slider to compare 2 images

Hi everyone.

I'm looking for a way (compatible or built-in with Opus Directory) to compare two images with a slider.

Something like this: https://www.dropbox.com/s/vyidm9koadt5h97/2018-07-18_04-24-43.mp4?dl=0

It would be amazing if it was included inside Opus Directory Image Viewer as a button to toggle the comparaison mode.

Thanks for your suggestion or attention from developers.
Kind regards,

Yvan

You could use one of the buttons/scripts on the forum that sends a pair of selected files to a comparison tool like Beyond Compare, which then gives you a slider to crossfade between the two images (among other image diffing/comparison modes).

In terms of what's built in, there's just the option of flicking back & forth between two images.
