Finaly i adopted another solution, seem's to work like a charm.
Each time a Label value is updated, i fetch every images using
getElementsByTagName in the domElement of the Label.
foreach image, :
* setAttribute "previousSrc" with actuel src
* change src with a blank image
* set an onload event launching function named "imageOnLoad",
* remove height/width attribute,
* change src with the original one
In the function "imageOnLoad",
* the parentNode of the image (so the div containing the Label) to "auto".
* fetch offsetHeight of this same div, computed by the browser.
* finaly, set the height of the label with this offset using setHeight.
Cheers
In think this poorly hack can be used on embed.Html too.
