Magento 2 - Remove Fotorama Caption from Product View Page

Unfortunately there is not currently a way to remove with admin panel options or layout xml update. Easiest thing to do is just set a display:none property.

& when (@media-common = true) {
    .catalog-product-view {
        .fotorama__caption {
            display: none;
        }
    }
}

There is a property "showCaption" which is set to true by default in fotorama.js You can set this to false from gallery.phtml

It's Fairly easy though. Override view.xml file in your theme, Find:

<var name="caption">false</var> <!-- Display alt text as image title in fullscreen(true/false) -->

Enable - Disable by true/false, Clear Cache and see the results.

Let me know if this helps.
