Duplicate images for screenshot toggle?

[Elissa Miller]

Hi, H+M team:

I'm creating webhelp that will be used on an Android app designed to run on low-end and legacy devices, so storage space and screen space are both at a premium. To keep images from overwhelming the small screen, I've been using the screenshot toggle at 25% of image. In the /images folder, I now see two versions of every image: the original whatever.png and a new whatever_zoom25.png. (I realize that you already know this, but I need the runway to get my question.)

Is there a way to modify things so that instead of creating a second space-hogging image, a single existing image is displayed at 25% of the original size and then at full size when tapped/clicked? Is this something that could somehow be rigged with JavaScript?

Worst-case scenario is that I eliminate all screenshot toggles and replace them with a regular toggle switch to display the full-size image, but the UX isn't as pleasant as being able to see the thumbnail, but if it's theoretically possible to customize the screenshot toggle, we're willing to spend some developer time trying to figure it out.

Thanks as always,
E Miller

Hi Elissa,

Unfortunately, toggles need both images to work, it's just the way they work. Note also that when you scale regular images in the editor, this is non-destructive and the entire original image is still exported, just with a scaling attribute. So if you're targeting low-overheads devices you need to keep the original image size down at source.

This being said, there is a solution for this if you use a skin from the Premium Pack add-on. For some time now, the skins from the V3 and above series in this pack have included a feature called "tap images" that is designed for precisely this situation. See here in the Premium Pack documentation for details:
