JetSloths Image Choices 1.2.0 addressed a heap of updates and fixes, but more excitingly introduces a new image lightbox feature to allow image enlargement on any of your image choices.
Image Choices Lightbox
You can now turn on the lightbox for image choices enabled fields. This will add a zoom/enlarge icon button on image choices in that field, opening a larger version of the image in a lightbox gallery. Select the image size to use for the lightbox in the Image Choices form settings.
Using the Lightbox feature
Thankfully, we’ve made this super simple. Once you’ve got the latest version of Image choices 1.2.0, to activate the lightbox feature, go to the field appearance tab and tick on the checkbox.
Note: if you’re enabling lightbox on an image choices field created before this update, you will need to remove and re-add the images.
You can control the image size that is output within the lightbox via the Image Choices settings page.
To grab the latest version of Image Choices, currently, the best and easiest way is to log into your JetSloth account and download the latest version.
