    I am using a plug-in (ArtDisplay) that pulls and displays a product image via an app for AR or in a mock-up room. I would like it to pull and display the current product variation image since those are different color, etc.. I have tons of code that I’ve found online and have figured out how to pull the variation image ID, I just can’t figure out how to forward that to the widget to keep it updated. I’ve only played around in the widget’s , but maybe I need to be looking at the main widget php. If you believe you are able to solve this problem, send me a quote and I’ll get back to you.

    We have created a game of ranking formula 1 drivers using Excel. We have been successfully playing the game using Excel the past years but it has gotten quite big in that we dont have the manpower anymore to handle each game on Excel anymore. We are now looking to put the game on a website or preferably on an App, such that we can actually start playing the game with automatic updates and scale it up. What we are looking for is a front end web/app developer that can take the underlining structure we have already build for a web game and turn it into a fully developed website / app. The game is quite simple and does not require much. However, we do want to have a solution already now that can be scaled up quickly.
