Hi,
Jetpack publishes the right article and content but the wrong image. About 50% of the articles are completely right (it seems that are mostly article which are from me). The other half get's wrong images like this one:
http://disctopia.de/reviews/heavy-metal-iron-dogs-free-and-wild-11995/
We already have another plugin installed to ensure that all images are between 500x500 und 1000x1000px. All articles also including featured images.
Can't see why it won't work for all articles.
regards,
martin
