T3 Automatic image reduction

The image autoresize extension has recently been activated on all Typo3 installations managed by RHRK. This automatically tries to reduce the file size of large uploaded images by scaling them down to a maximum of 1920x1920 pixels (usual image width for Full HD). In future, this will save editors from having to downscale manually before uploading.

Files that have already been uploaded will also be downscaled as part of the planned web relaunch in order to save storage space.
