Hi Rick,

Thank you for getting in touch with us. My name is John, and I'm happy to assist you today. I appreciate your patience while we've been working towards your ticket.

I'm not exactly sure what do you mean. When you insert images from the WP Media Library, LayerSlider stores special identifiers from which it can pull the images on-the-fly. It should always reflect changes and respect 3rd party integrations to give you an "up-to-date version" of the image. 

Can you please provide more information and examples? How the images were altered? Which tools/plugins did you use?

This has nothing to do with LayerSlider. The Media Library is just a big folder full of uploaded stuff. How should a plugin or WordPress make sense of randomly appearing and disappearing files without telling them which one they should use? They have no way of knowing if new files are a replacement and for which images.

One way of doing this is directly via LayerSlider. You can delete files in the Media Library when opened from LayerSlider, then immediately add the new one in the appropriate place.

But more likely, what you need is a replacement functionality in the Media Library. WordPress doesn't offer this out of the box, but there are plugins and other ways to achieve it. Quickly searching for this, here's the first Google result: How to Easily Replace Image and Media Files in WordPress

LayerSlider will follow the changes made on images that was replaced this way. Also, LayerSlider has an image editor, so you can consider using it for convenience when you only want simple modifications.

Thank you for the clarification, Rick! This really should work. 

However, it's still not related to LayerSlider. There is no force refresh method because LayerSlider is doing it at every page load on its own. As mentioned, we aren't storing images or even links to images. We're storing an identifier, from which WordPress sends back the image details on the fly. It's a standard that we're following the way the WordPress Devs intended. 

Many things can cause why you see older versions of the images. A CDN network if you're using one. The cache of the web browser. Optimizer plugins. It's also a question of whether you're editing files directly or using the Media Library to delete and re-upload the file. Based on your description, it's the latter. However, I'm not sure how WordPress handles essentially duplicate uploads. A lot is happening in the background, like analyzing and storing image information, generating various uploaded image sizes, etc. While it's not likely, a 3rd party plugin can also disrupt this use case.

I understand that this might not be the response you were looking for, but I don't see how this would depend on LayerSlider. I truly believe it's on something else, and that you should try to empty the browser cache and look through the other options to find a solution.
