I have an issue with "submitted-image-url" option when post a share using LinkedIn API. All my images stored on Amazon S3. For example "https://s3.amazonaws.com/news-img/client_619/619_1424690228983-DarthVaderSEOToaster2.jpg". When I try to use different source for image, from whatever another website, it works well.
Could you please help me? Why images from Amazon S3 cannot be fetched by LinkedIn? Do I need add some exceptions in my S3 bucket?
One more, with other social networks like Twitter and Facebook everything works fine.
Thank you, Oleg
Tricky http headers... Need to set correct 'content-type' header when upload images to S3 bucket. E.g. 'Content-Type': image/' + imageExtension. Solved!
