vimeo, youtube and dailymotion icons not showing in editor

[plongeur.com]

Hi, my forum is in 5.2.5 at the moment.

When i go in the "adanced editor" there are 3 buttons for YouTube, vimeo and Dailymotion integration but the icons of these providers does not appear, so the buttons are empty.
It seems the icons are supposed to be there :
/forums/images/editor/vimeo-icon.jpg
/forums/images/editor/ytube.gif
/forums/images/editor/dmotion.gif
But i can't fidn them, i dowloaded again the full package for vbulletin and i can't find them either.

Does anyone have this problem ?
Where can i find the icons ?

Thanks & best regards.

Just so it is clear, a screenshot is better than a thousand words :

There's no such buttons in the default editor. Are these custom buttons? Most likely, the image paths are wrong.

You have custom BBCodes and the image paths are wrong. Inspect the button using the browser dev tools to check the image path and from there you will know how to correct it in the BBCode settings. If the path looks correct, then the images are missing from the server. In that case, you have to upload them.

The forum is migrated from version 3.0.
is there a chance this is inherited from this version?

I'll check Custom bbcode asap.
