To edit an image, select it and click 'Apply affected & more' in the settings menu.

Once clicked, a customization window will be opened where you can crop, customize and add text and filters.

The crop function lets you select proportions for your image, or you can drag its corners to the new cropped size and click 'Apply'.

A catalog of filters can be added to match the color profile of your image to the email.

You can also add text to your image. Customize the font, size, and colors easily to create professional-looking promotional material.

Once done, save and exit it, and it will be loaded into your image content block.
