Hi there. I am on 7.19.30 Confluence Data Center.
I have faced an issue when {viewdoc} macro doesn't show images. I tried to find any solutions here. These I checked and it didn't help:
1. https://confluence.atlassian.com/confkb/viewdoc-macro-not-loading-images-1431964292.html
2. Create page, then upload file and use macro.
3. Shut down Confluence, clear plugins' cache, Start Confluence.
I ll be glad if you can help me!
