Website designing problem

[tanush_89]

Hey guys,

I've been searching a lot but I couldn't understand the working many websites like this one:
Personalized Wine Bottle Stopper

Please can anyone explain me how I can edit pictures according to what user demands?

Which technology is this ?

I hope I can get an answer

I think JS is used to open the preview in a new page but is it also used to edit image?
