On the backend-page of the image-module (menu > modules > all > image) you can edit images with the use of presets.

To add a new preset, go to the the tab presets. Here you can see all existing presets and you can edit and delete them. With a click on add preset you will add a new preset. Type in the name, choose the preset and click on the plus-symbol. Afterwards type in the values and click on add. You can add more editing-parts and sort them via drag and drop. To change a existing preset, click on the edit symbol. At the end you have to save the new and/or edited presets with clicking on the save-button.

if you want to add a new content element of the image-module, you can at the selection of the images choose a preset as well. Here all you all created presets stand by.
