I have checked the flexinode project page and there seems to be several problems associated with 4.7 and image fields in flexinode. My issue: the images that are already added to flexinodes through flexinode fields will no longer display (a red X appears). If I try to edit the flexinode, Drupal tells me that I must supply the required image, even though one has already been uploaded. If I try to upload a new image, however, it still won't upload a new image and still gives me the message that the image is required.

So, this is perhaps a path issue. But it seems to be more of an issue with flexinode itself, and not just my theme.

Any suggestions would be appreciated. Thanks in advance!
