Image Editor
With the Image Editor, you can rotate, resize and crop your pictures. Click on a image icon in the left navigation area and then choose "Edit in image":
All following operations are currently not undoable, so be careful, what you do or keep a copy of the original
Rotating
For a quick rotating, choose right (90° clockwise), left (90° anti-clockwise) or 180°. But you can also rotate with any degree wished, just type something between 0 and 360 into "Any value".
Resizing
You can resize a picture to any size (besides that it doesn't make much sense to make pictures larger ;) ). Fill in the "Width" and/or "Height" field. If one is left empty, the picture will be resized proportionally.
Cropping
The yellow box on the picture is used for cropping the image. You can drag it around to put it into the right position. With holding "Shift" or "Control", you can change the size of the cropping box. You can also define, if this resizing should be done proportionally or not with the 2 radiobuttons on the left side. When you're satisfied with the size of the box, hit "Crop" to actually resize the image.
