fotorama__stage size

[seasterling]

I'm trying to change the size of the fotorama gallery, but can't figure out where fotorama__stage and fotorama__stage__shaft are getting their width & height attributes. Anybody?

Overwrite `vendor\magento\theme-frontend-luma\etc\view.xml`

I have the following, for example: `app\design\frontend\[CustomTheme]\default\etc\view.xml`

<view xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Config/etc/view.xsd">
    <media>
        <images module="Magento_Catalog">
            <image id="product_page_image_large" type="image"/>
            <image id="product_page_image_medium" type="image">
                <width>700</width>
                <height>420</height>
            </image>

            <image id="product_page_main_image" type="image">
                <width>700</width>
                <height>420</height>
            </image>

            <image id="product_page_main_image_default" type="image">
                <width>700</width>
                <height>420</height>
            </image>
        </images>
    </media>
</view>

 This will cause the `fotorama__stage` to be smaller - it adjusts based on the image size.
