adding loading css class

For big image, intense do nothing during image loading.

Adding an css class to styling element while image loading

Hmm, this is definitely a bug, although I think this fix isn't quite the right fix. Will want to build a little spinner (something that is probably built with js & css animations, but still contained within intense.js), that goes off when the image is loading, and then reveal once its complete, with the image gracefully fading in.

Hopefully I can take a look this week, and see if your changes work well towards that!

Do not build a spinner with intense.js, just provide the js event or the css class, there're lots of awesome spinner library such as spin.js.

You should build intense.js as a library not an application.

Intense.js should be stand alone, and easy to use for anyone which I feel should involve a simple loader. Its not worth providing a semi-broken experience with "you need to use X and Y" to have it working as it should.

I agree with @TimHolman a simple loader with a Callback on load will do perfectly in ~10 lines of js

Since this is a small part of #10, I'm merging it in, and closing this branch of the issue.

Thanks for the pull @thi3rry, will take your code into consideration for the fix!
