I'm working on creating a full screen expandable ad with a photo gallery in it. Will the page speed be affected by the size of the images in the photo gallery or is the HTML5 generated by GWD smart enough to only load the images when the ad is clicked (since the gallery is on the expandable screen and not the main unit itself)?
If it's not, any tips / tricks to making it "lazy load" so the ad does not affect the overall page speed?
Your feedback is appreciated.
