Image link from link wizard can't be used in image VH anymore
In simple input fields you can select an image by using the link wizard (use case: in flexform sections you can't use a normal FAL relation because those are relations to a record and not a single field of a record). In TYPO3 v7 such a link had the form "file:<uid>" and this could be used in e.g. the src attribute of the image viewhelper.
In TYPO3 v8 such a link has the format "t3://file?uid=<uid>" and this is not supported by the pre-processing for the image viewhelper.
In the Extbase ImageService support for this can simply be added.
