You can place the file view.xml in your theme's /etc directory with contents like this:

<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_small" type="thumbnail">
                <width>68</width>
                <height>80</height>
            </image>
        </images>
    </media>
</view>

One more thing product images in gallery will come as per your product galley container. If you want to more image in your gallery without arrow navigation..then observe height of your product gallery container then resize image as per that. Like if Container height is 350 then

<width>68</width>
<height>70</height>
