Add a option imgFallback which use img element's data-src attribute when

src attribute is missing.

Appreciates! It's a good solution to solve some initial problems. But in some situations like following:

<img data-src-origin="my-pic.jpg" data-src-thumbnail="my-pic-50x50.jpg" />

It can not work any more, so how about define the imgFallback to be one of following types:

• Boolean Get the source of image by node.data('src') instead of node.attr('src').
• String Get the source of image by imgFallback, e.g.:
  • data-src-xxx: 'node.data('src-xxx')`.
  • prop-src-xxx: 'node.prop('src-xxx')`.
  • src-xxx: 'node.attr('src-xxx')`.

• Function Get the source of image by imgFallback(node), e.g.:

  {
  imgFallback: function(node){
    return node.attr('base') + '/' + node.attr('rel-path');
  }
  }

What do yo say?

I'll update the PR. Just to make sure, what you suggested is only applicable when src attribute is missing, right?

[entertainyou]

Pushed the update, and cheerio does not support .prop function, so only data-xxx or actual attribute is supported.

Merged, thanks!
