Independent software developer Brian Webster has released iPhoto Library Manager 1.0.
iPhoto is Apple's Mac OS X-only digital-image-management utility, announced at Macworld Expo, San Francisco. It's designed to make it easy to import, edit and print digital photos. It can also organize and manage an entire photo collection containing thousands of images.
iPhoto Library Manager 1.0 lets iPhoto users work with multiple photo libraries, or save libraries in locations other than the one it chooses. The utility also lets multiple users share a common photo library, and controls the access permissions of all the files within libraries.
Separate preferences are stored for each library, and the utility is fully AppleScriptable, so scripts can be written to view various libraries, saving the hassle of switching between libraries manually. The utility is available for free download.
