Whats new in version 4.1.7:
- Fixed an error that could occur when copying flagged photos with iPhoto 9.2.x
- Worked around an OS X bug that could cause some photos not to be copied when dragging a large number of photos at once
- We now show an error message when trying to create or add a library on a drive whose format is unsupported by iPhoto (e.g. FAT-32)
- Fixed a crash on startup when the path to iPhoto\'s current library was empty or otherwise bogus
- Fixed a spurious error message that could appear when trying to copy photos to an Aperture library
- Added an option to skip the preview stage when merging
- Fixed an issue where dragging files on top of a library whose name was being edited would append the file paths into the library\'s name
- The "filename + date" duplicate comparison now recognizes three digit suffixes appended to filenames, e.g. "foo.jpg" vs. "foo-002.jpg"
Publisher review:iPhoto Library Manager is a plug-in for iPhoto that allows you to better organize your photos in folders creating multiple image libraries. You can quickly switch from one library to another and copy a photo preserving subtitles, keywords, comments, notes, dates, etc.. IPhoto Library Manager offers functions for dividing a heavy file into several parts and conversely, as well as a module synchronization with your iPod.
iPhoto Library Manager allows iPhoto to use several photo libraries stored in different locations on the hard drive.iPhoto Library Manager can set up multiple photo libraries, but also allows you to copy photos from one library to another or to simply switch between them.
Requirements:Operating system:Mac OS X 10.6.8 or later
