Hello there,

Welcome to your support management and thank you for choosing our theme!

First please try using the following plugin: https://wordpress.org/plugins/regenerate-thumbnails/

in order to regenerate the thumbnails and make sure that that was not creating the issue.

If this does not help please make sure the images you upload are of high quality and at least twice as large as the space you'd like to present them in.

Hope this helps! If not please provide us with your wp-admin details(in a private ticket) so we can log in and investigate this further.

If there is anything else that we can assist you with please don't hesitate to ask.

Kind regards,
Sean

Hi there,

Even though the original images are fine, these options for Post Item size are set in WPBakery page builder, it creates a new images with these new dimensions, and those are the images it is using on your desktop site:

So when you are viewing it in mobile view the images width goes to 100% percent, which is usually a few times the width of the dimension you set before, and so it looks blurry.

I can suggest that you override the width of the images for mobile view if you insert the following CSS code into Appearance > Customize > Additional CSS:

@media only screen and (max-width: 600px) {
    .eltd-bnl-holder .eltd-bnl-outer .eltd-bnl-inner .eltd-post-item.eltd-pt-two-item .eltd-post-item-inner .eltd-pt-image-holder a.eltd-pt-image-link {
        width: 75px !important;
    }
    div.eltd-post-block-part:not(.eltd-post-block-featured) .eltd-post-item-inner {
        display: flex;
    }
}

Now these images will contain the original dimensions that are set in WPBakery Page Builder, and you'll got something like this:

Let us know if this works for you, or if you need any further help.

Best regards!
