Drupal image fields allow content editors to upload photos and pictures without tedious manual cropping and scaling. One posted, images are piped through a series of automatic cropping and scaling presets, ensuring everything is fast and consistent. Unfortunately, all that automation can be a problem when content creators do need to tweak how an image will appear at different sizes. When that's the case, the Imagefield Focus module can help.
Although it doesn't give editors explicit control over the precise appearance of every version of an uploaded image, Imagefield Focus does the next best thing. It's a quick and easy addition to most sites, and can dramatically improve the quality of small thumbnails when used judiciously.
