title: Storing .jpg files in local storage
body: <p>I am trying to find a way to store .jpg files from my website into the localstorage to increase the site speed.
  Theoretical its simple: convert the picture.jpg into a base64 string and store it with setitem into the localstorage. to display the picture again just load the base64 string from the localstorage and decode back to jpg. But, as always, the practice is more difficult. Im trying to find a way to convert the .jpg files on-the-fly to base64 using html5 or javascript (no php!). Does someone had the same problem and was able to find a solution and could share the code?</p>
