Edit
webPhoto uses the RubyCocoa bridge to tap in to Apple's Core Image library. This allows fast, non-destructive editing. All edits to a photo are saved into a "recipe" that webPhoto applies when ever it needs to re-render a photo. The original photo is never altered in any way.
Editing interface

Double-click a photo to switch to the editing view. Drag the border around the image to live-resize it.

Rotate

Click the green rotation arrows to rotate the image in 90 degree increments.

Crop

Use the crop tool to select a region of your image to crop to.

(result of crop)

After selecting a crop region, the photo redisplays with its new dimensions.

Add effects

Use the effects sliders to transform your photos. As with all operations, these are non-destructive.

Thumbnail updated with changes

When edits are complete, the photo's thumbnail is updated in the browsing view.
