1. The answer is here http://www.nextscripts.com/snap-features/how-snap-sets-images/
2. General autoposting speed limit is per post, not per network. It designed for the situations like where you import 10 posts at once, they will be posted one by one, not all 10 at the same time.
if you need to set delays per network, please look here: http://www.nextscripts.com/snap-features/scheduled-and-delayed-posting/
Still not solved.
I want Facebook to decide which image to use, instead of the plugin using the featured image. I have ‘Let Facebook fill the link info’ checked, yet it is still using the featured image from the post.
When other people share posts from my blog on their own Facebook pages, it grabs images correctly (I have the Yoast plugin adding open graph meta data).
When ‘Let Facebook fill the link info’ checked plugin does only one thing – absolutely nothing. It just sends Facebook a plain URL without any additional info. No image, no description – nothing. It won’t be possible to use featured image or selected image. Facebook does all by itself.
When I manually paste the link into facebook, the better (higher resolution) image automatically pops up. There is also an arrow that lets me scroll to select the lower resolution image (which I don’t want – you can barely see it).
For some reason when it comes through nextscripts (with ‘Let Facebook fill the link info’ checked) it automatically picks the lower resolution image.
The reason is simple – your lower resolution image is first in your OG tags.
OK, I think I got it now. Instead of fixing the OG tags I just set it so that the plugin attaches the blogpost and fills the info – looks pretty close to how I want it. Thanks for your help.
