I have a good understanding of HTML and CSS, but I'm struggling with JavaScript. I noticed that there is a script adding "=s1400" to the image path which is causing the image not to load. You can see the URL is (source files can be viewed using Chrome DevTools).
Original HTML:
<img id="vbid-cfb2edc5-mm7avm4t" class="blocks-inner-pic preview-element magic-circle-holder load-high-res shrinkable-img" data-menu-name="HEADER_IMAGE" src="https://zenith-express.com/imgs/af_service_area.png" data-orig-width="688" data-orig-height="420" />
Modified HTML:
<img id="vbid-cfb2edc5-mm7avm4t" class="blocks-inner-pic preview-element magic-circle-holder shrinkable-img" data-menu-name="HEADER_IMAGE" src="https://zenith-express.com/imgs/af_service_area.png=s1400" data-orig-width="688" data-orig-height="420" data-width-before-shrink="700" style="background-image: none;">
