There are plenty of configuration options available and you'll likely spend some time with the settings before you start working with the extension. To access the configuration, navigate to:
Joomla Backend / Components / JoomProject / Designs / Options
General
Image Album Cover Size
The album cover is the first image displayed for each album. The generated image may show the center of the original image, if it cannot fit the entire image into the selected size.
Image Preview Size
The previews are small images displayed on all Design pages. The generated image may show the center of the original image, if it cannot fit the entire image into the selected size.
Image Full Size
The full size images are displayed when looking at a specific design or revision. The generated image will always retain the aspect ratio of the original file. It will try to match the selected width, and proportionally scale down the height. For example, if you've selected 1280x720px (16:9), and upload a file that has 1920x1200px (16:10), then the resulting image will be 1280x800px (16:10).
Text Watermark
Enable or disable text watermarks. When enabled, all generated images will include a semi-transparent text, usually a copyright notice, at the selected position.
Watermark position
Select the position of the watermark in the image.
Watermark String
The watermark text string to show on the images. If left empty, a default text will be used.
Approval Behavior
Here you can decide whether non-admins are allowed to revise their approval decision or not. This can be useful if you want your clients to make a binding decision.
Upload Directory
The location on the server where all uploaded images will be stored.
Increase Memory
Depending on your server's default settings and on the size of your images, you might want to increase the memory here. Please note that if your hosting provider does not allow you to change the memory limit, this setting will have no impact.
