Incorrect images can come through to dlvr.it or to any of your Socials for a number of reasons. Most commonly, this is because your Open Graph tagging in your Metadata is pointing us to an image that you did not intend. We prioritize images with Open Graph tags over other types of images. Facebook also primarily does this. Here is an example of what this looks like:
--This is an example of a post with an image:
--Here is an example of the metadata from this post:
The metadata above indicates which images are tagged under the og:image tag. This tag will have a link next to it, which will direct to the image. In this case, the image size is also specified within the link (764x400).
Another reason that the wrong images may be posting is that the Open Graph image may not meet our requirements for images. Images must be a minimum of 150x150. If the Open Graph image does not meet this requirement, we will disregard that image and look for any other image in your enclosures that fit this requirement.
The final reason that the wrong images may be posting is that you are directing us to the same link for all of your Posts. If this is the case, we will automatically cache images from the first post and use these images for any subsequent posts within 12 hours.
If you have any questions about your image posting in your account, please contact us at firstname.lastname@example.org.
