quick example: you have a car on an ecommerce site. you click on: [] add stickers checkbox then, an image overlay of the stickers is placed on the car. Is this possible? Can someone point me in the right direction - thanks so much!
This should be easily possible through jQuery. See http://www.sohtanaka.com/web-design/fancy-thumbnail-hover-effect-w-jquery/
If you do not need animation, you just need to change the offsetLeft and offsetTop. If you do need animation, you should use a timer (setInterval) that shifts the sticker by a few pixels until its position (style.left and style.top) reaches the car.
