Well, I came up with three options, none of which are perfect but one of them might work for you:
-
Convert each image to a PDF and display it in the PDF Viewer in Thunkable. I think this is your best option and it allows for pinch zoom.
-
I managed to enable pinch zoom on my iPhone in Thunkable Live using this javascript but only for cloud-hosted urls: Pinch and Zoom with native JavaScript. I couldn’t figure out the local path to the file.
-
I tried to do this with sprites which is a constraint and it doesn’t allow pinch gestures: User resize the image - #2 by tatiang
