I've been struggling with this issue for a while. I am unable to get the image to show on the preview section of the Picture Library. I've checked to ensure the content type was correctly set and also that the thumbnail images we're being created. I ran out of ideas, is there anyway to reset the picture link of the thumbnail image so it points to the proper thumbnail picture?
Based on your attached screenshot. It looks like you are not using
Picture Library,and You may use a document library and you have allowed content type and add the
Picture content type or any something else.
What proves that this is not a default
Picture Library : in default, you can find
New Picture link rather than
So If you don't have any reason to do that , I suggest to create a new
Picture Library by adding a new app >
Picture Library that should be working properly.
After searching for a solution I've located the actual problem. If you look at the attached picture you'll see that the link to the thumbnail preview seems to be broken which is why i get the black boxed "X".
So now my new issue is figuring out how to reset or get the script working so that it can pull the proper image from the library.
