All widgets have their own predefined image resizing and cropping options. They can be changed in administration panel Developer -> Modules config -> Content management

Available options:

• Height - image height
• Width - image width
• Quality - a number from 0 (low quality) to 100 (best quality)

New setting apply only for new uploaded photos. Old photos are not resized automatically. All themes goes with parameters file that should be imported to set correct cropping options for that theme.

Each widget can have many different layouts. For example, text/photo widget by default has four layouts: left, right, small left, small right. You can set additional layouts by overriding default configuration file of a widget.
