Presswell Art Direction

Presswell Art Direction helps simplify how custom image thumbnail sizes are defined, cropped, and generated.

Features

• Control image cropping with hot-spots
• Select custom image sizes in the WordPress editor
• Dynamically generate image thumbnails
• Delete all cached thumbnails

Image Cropping

Presswell Art Direction adds the ability to set a focal point hot-spot for all images in the media library for fine grain cropping control. Simply identify where the subject of the photo is and the plugin will crop all custom image thumbnails to ensure it stays in frame.

Thumbnail Sizes

Presswell Art Direction adds an easy to use interface for defining and editing custom image thumbnail sizes. Custom image sizes will be available for selection when inserting images in the post editor.

Dynamic Images

Presswell Art Direction prevents custom image sizes from being generated automatically. Only standard WordPress thumbnails will be generated when a new image is uploaded. All other image sizes will be dynamically generated when called via code or requested via URL, saving server space when many custom image sizes are defined. Note: URL based image generation requires that pretty permalinks are enabled.
