Title: Insert an ob_clean() prior to header output

It seems that in some rare instances not having this ob_clean()
apache might output some potentially wrong headers and the image
is output without any dimensions.
And the browsers do not manage to detect the image as valid
Thus assume that the image is corrupted.
