@Arkadiusz Wroblewski are you seeing this odd behavior with all images or only some of them? Are you able to add small size images?

@Tinker Fadoua 

From time to time, yes. But currently I’m migrating a large department where I have to do a lot of scripting and handle several smaller instances, so I don’t really think of it as anything special, as temporary Hiccups are normal.

I will observe it More.

Sounds like a plan. Keep us posted please.

Hello @Gokul Patil 

Yep, seen that a lot in Jira Cloud. “Preview unavailable” is usually Jira saying “I can’t render/fetch that image right now”, not that the ticket is broken.

Most common reasons:

It’s not a real Jira attachment

People often paste images from Teams/SharePoint/Google/Slack/web, and Jira ends up showing it as an embedded preview. If the source link needs login, expires, or gets blocked = preview dies.

Fix: download it and attach it directly to the issue (drag & drop / Attach).

Browser / network is blocking it

Adblockers, strict privacy settings, or a corporate proxy/VPN can block Atlassian’s image/CDN calls.

Fix: try incognito, disable extensions, or test another network.

Platform hiccup

Sometimes it’s just Atlassian having a moment and previews come back later.

Fix: hard refresh, open from the Attachments section, and if it happens to many users at the same time, check status / log a support ticket with a few issue keys + timestamps.
