Gravity form product variations.

I am working on photo album project. It's kind of online photo album creation system. Once user will create photo album, after that user would be able to purchase it. More than 80% project has been done. I just need someone to help me out on one step. Overall project is very lengthy. I may offer you more tasks will pay extra for it. (if it required) Actually, i have to get lot's of details from users. Such as width and height of album, what type of material .... etc I am getting all details through form width radio buttons, drop downs, and with text field. Form split in 5 sections with progress bar. Everything is setup nicely dynamic price generating as well as user add additional aspects in product. What you have to do just add product image variations on it. For example if user sleet grey color of album cover then album cover needs to be change into grey color in product image section. For more clear demonstration i have attached an YouTube video. This guy used gravity form and it works absolutely fine. When he select yellow controller and then image on right side changes into yellow controller. This is what i want. [login to view URL] I know woocomerce does have product variations as built in feature, but i can't use that because i am using gravity form. Gravity form doesn't support those features. It doesn't works proper at all with gravity form. I have already tested it. I guess only way to sort out this, I need a geek who can do some custom code. Gravity form all field provide value so you can pass it through with your code. It would be lot easier for someone who knows that.
