Blogger added a 'Lightbox' feature which is the same as Google+ handles pictures.

There is no way to disable the lightbox. There is not an option and even removing the link doesn't help.
But there is a workaround which seems to be working. In that case remove the link from the image en then add a new link to the image with: javascript: void(0); |
