The problem is that alfresco is not directly accessible through the browser. My webapp which is talking to Alfresco needs a method to get this content from the Repo and display it as an image. Quickstart somehow achieves this but have not been able to figure it out.
I can make a http request from my Webapp server and get the image content but now I need my webapp (which is running quickstart) to output this content and update the content type so the image renders.
If you pest this directly in address bar you will be able to see the image. Now if you embedded this in your page then it should fetch the image from the repo.
