Web apps

I have skills in HTML JS PHP and …
and I want know how can I write web apps like pixlr or picmonkey or chrome.angrybirds.com or etc.
Is any book or tutorial about it ?
For example how can I write a simple web based paint application that can save painting image ?

Hi,

pixlr and angrybirds use Canvas for the rendering, picmonkey uses flash.

MDN is probably best source for javascript info / tutorials.

Hope it helps,

Your question is basically “I can use a hammer. How can I build a car?”.

No, there is no single tutorial that will teach you how to do these things because they are a joint effort amongst very clever and capable designers and developers using multiple cutting-edge languages and most likely with centuries of collective experience in the web.
