[TYPO3-english] Upgrade to 6.2 - missing images in backend

[Gunnar Jonsson]

I have upgraded from Typo3 6.0 to 6.2. Everything seems Ok. However, all the uploaded images has disappeared from the page contents in backend. Now only the filename is listed in the page content in backend. Is there a different handling of the images in backend in Typo3 6.2? Is there any variable to set in order to get the images back in backend. It is no problem with the images in frontend, only in backend. 
regards,
