I have a Java web app that connects to Salesforce to pull catalog information, etc. Today, the images on the page that are stored on Salesforce are showing up as broken links. When I visit the link for the image, I'm able to view it.
Using Chrome Tools, I found that the image being returned on the page is of type "text", rather than "image". This problem only occurred after Winter '15 was rolled out to this sandbox. Other sandboxes that are still using Summer '14 are working correctly.
This link works (when logged into SF admin): https://c.cs7.content.force.com/servlet/servlet.FileDownload?file=FILE_ID
This URL does not work: https://c.cs8.content.force.com/servlet/servlet.ImageServer?id=ID&oid=OID
What could be causing this?
