public static resize ($file, $width = 140, $height = 105, $style = 'cover', $format = 'jpg')
If it can, it creates a cached thumbnail of the specified
image file, saved to cache/thumbs with the name
md5($file) plus -WIDTHxHEIGHT.jpg. If it can't create
the thumbnail, the original will be returned with one of
the following messages added to it as a hashmark:
If the cached version already exists, and its modification time
is newer than the original, then the cached version is returned
This makes first requests to a gallery page expensive, but
subsequent requests much faster.
public static reorient ($file)
Fixes the orientation of a JPEG image based on its exif data.
Note: Requires the exif PHP extension, or it will simply
return the original image untouched with the following
hashmark added: #exif-missing.
public static generate_key ($key)
Generate a unique key for embedded image spots.
public static for_key ($key, $image)
Get or set the image associated with a key.
