This documentation is not using the current rendering mechanism and will be deleted by December 31st, 2020. The extension maintainer should switch to the new system. Details on how to use the rendering mechanism can be found here.

Users Manual

This chapter describes how to use the extension from a user point of view.


Simply upload your unmodified pictures either from the File > Filelist module (fileadmin) or from the edit form of a content element (text with image, image, …) and enjoy the automatic resizing and orientation in portrait of your pictures (here with an original picture in 4080 × 2720, 3.6 MB with EXIF orientation set to “portrait”):

Example of an image that has been automatically resized

As you see, the constraints of 1024 × 768 pixels have been taken into account even with the correct orientation of the picture. If the reorientation did not have been taken into account, the picture would have been resized to 682 × 1024 instead (maximum ratio using the other dimension).

Here is another example, from a content element “text w/image” where a BMP (screenshot.bmp, 3.2 MB, 1184 × 884) has been added to the list of associated images:

Example of an image that has been automatically converted from one format to another

The uploaded file screenshot.bmp has automatically been both resized and converted to a new file screenshot.jpg (according to the image type conversion mapping option described in chapter Administrator Manual).

Details of this image show that its footprint is now quite small (151 KB):

This extension is fully compatible with FAL (File Abstraction Layer) introduced with TYPO3 6.0. When an image is resized or converted from one format to another, the corresponding index in FAL (together with associated metadata starting from TYPO3 6.2) is updated accordingly.

Adobe Illustrator
Windows OS/2 Bitmap Graphics

Tagged Image Format
