Add, Resize and Crop Images in existing websites Image Gallery.

Hello,

I currently have an existing website with an image gallery. I would like my customer to be able to add, resize and crop images to the existing image gallery using perches CMS. The cropped image size would be 650px by 400px;

Any instruction and/or documentation on how to do this will be helpful.

Thank you,

Aaron
