Override the image scale for layers in your HTML exports

If you would like to override the image scale size for any layer in your timeline, you can optionally do this for any layer by clicking any layer's Settings icon button in the main timeline to open the layer settings, and selecting an option from the Optionally override the image format for this layer in banner exports dropdown select list:

Use Global HTML Export 'Retina' Toggle Setting (Default)
Export this layer at @1x Resolution
Export this layer at @1x Resolution (Retina)

This will ensure that your layer will always be exported at the scaling resolution that you've selected when they're exported to HTML from the Bannerify plugin.
