[TYPO3-english] Error Not Acceptable on Click enlarged images

[Russel Anderson]

I can't guaranty but it looks like this 406 error is triggered by 
mod_security (apache module). Get your hosting provider to look at the 
logs and ask him to disable this specific rule for your domain.

Worth to investigate if you are not ready to upgrade...
