TS6 (6.0.0 Beta 3.4) bug: `[IMG] ts3image://` path requires trailing slash (breaks TS3 compatibility)

TeamSpeak 6 Client
, , ,
1

Versions / environment

  • TeamSpeak 3: 3.6.2
  • TeamSpeak 6: 6.0.0 Beta 3.4
  • OS: Windows

Summary

There appears to be a difference in how TeamSpeak 3 and TeamSpeak 6 parse/normalize the path parameter in ts3image:// URLs used in BBCode [IMG].

In practice:

  • TS3 works with path=/Banners (no trailing slash) but TS6 fails
  • TS6 works with path=/Banners/ (trailing slash) but TS3 fails

This makes it impossible to post a single [IMG] ts3image://... tag that works on both clients, which breaks backward compatibility.

Reproduction (100% reproducible)

Case 1 — Works on TS3, fails on TS6

[IMG]ts3image://v6-1-3.gif?channel=10&path=/Banners[/IMG]

TS6 log:

[2026-02-17 17:02:45.246] [info] Error opening file "C:\Users\Hannib\AppData\Local\TeamSpeak\Cache\Default\images\443859304d596c7376326b4447564b38755772765256616d6c525578772f555a792f615268426c6c7056453d\10/Banners\v6-1-3.gif": The system cannot find the path specified.

Case 2 — Works on TS6, fails on TS3

[IMG]ts3image://v6-1-3.gif?channel=10&path=/Banners/[/IMG]

TS3 log:

17/02/2026 21:30:12        Info    Failed to read image C:/Users/Hannib/AppData/Roaming/TS3Client/cache/remote/LwWmaxwocv7DJ410zAKBvYAJwwmOE7YVYeaRyD+6kJUS79ZP1dPqo+ujoOj5_B+vaFFOmKrSiEzKSVm+gEOSVw==

TS3 client console:

<22:24:58> Transfer "v6-1-3.gif" reports: (invalid file path)

Expected result

For backward compatibility, both clients (especially TS6) should accept both forms:

  • path=/Banners
  • path=/Banners/

(i.e., normalize the trailing slash in path before resolving the cached/local file path)

Actual result

  • TS6 fails unless path ends with /
  • TS3 fails when path ends with /

Impact

Users on TS3 and TS6 cannot share the same ts3image:// image/banners tag reliably across both clients.
