Image Mapper ‑ Shoppable Image

We were greeted with a blank screen when we tried to use the app, after many months of usage. Customer support was initially unresponsive, it seems like the shopify contact link for the developer is broken. once we found his direct email: lucdkny@gmail.com he was very responsive and fixed our issue very quickly.
The app is great, has just a little learning curve to use, but is exactly what we needed for our website.
