Well it was the 1st thing I did, but nothing happen. The gifs and images was still messy.I am not noticing any issues with the images or gifs in that thread. Try refreshing your cache (generally ctrl+f5 or ctrl+the reload button in your browser) and see if that fixes it.
Then I enter to "edit mode" the thread and write a preventive warning message about bugged pictures.
Then preview the edition, and the problem was solve in the render of the preview.
Then save (so another refresh), but here again the disjointed pictures and shortened gifs came back.
It came back to the normal since. But assuming the answers that bug solved itself with no interventions ; it may/could occur again. So bad I forgot to save with bitmap the screensave before closing client.
