Requirement full bleed image share Google+?

[DanielMulderNL]

Hi everyone,

Im sort of a Google+ nutter and I wanted to figure out exactly what is required for a full bleed image to appear for +1 share on the page itself. I got it figured out and I think it requires:

• canonical url
• og:image
• image wider then 506px
• type article or page (microdata format)

But sometimes it seems that pages without a canonical url still show full bleed image when shared as link when I insert the url directly into a google+ post. My question is if this could be a cached version of the page where it had a canonical url?

Don't really know if that anyone is interested but I made a simple tool that checks if a page meets requirements for having a full bleed image when share as link on Google+. Think I nailed it pretty close but can't seem to get the full bleed image to appear for the tool itself do:) Please dont ask. It's driving me mad already.

Try it. Take a blog post url, check it with this tool and then see for yourself if it's accurate. If not I would like to hear very much as it would help me pin point it better!

Examples of pages with specific no no factors for you to try are:
http://www.copyblogger.com/google-authorship/ (img to small)

that's a pretty cool tool Daniel

Those you mentioned have worked for me along with adding schema to show the description.
