No geotag info in images

[daku]

Thank you for the great library!

It looks like in this line the rest of the node information is lost, specifically the geotag information that our project needs. Would you consider passing along the entire node instead of just the width and height information of the image? I am willing to create a PR for this if needed.

Line 34 in 020cb40

var image = item.node.image;
