iPhoto Bulk Renamer lets you rename (or keep the name of) every photo in a particular album. All you do is choose the album, it presents you with an image preview, you type in the new name and it hit enter, the next image appears, and so on and so forth.
Enhancements:
- I and I : lets you insert a captured name just incrementing a number at the end
- Whole Album I and I : renames a whole album to one name plus a number (i.e. my photos 1, my photos 2, my photos 3 etc.)
- Load Status indicator.

The Mac OS9 file system (and ASIP file servers) have a maximum character limitation of 31 for either file or folder names. Mac OSX allow much longer file names than does Mac OS9.
X29-Renamer truncates long OS X file names for copying to OS 9.
At best these longer file or folder names get truncated with names ending in what is "gibberish". At worst, when attempting to copy a folder containing a few of these files with longer names, the copy will be prevented thereby requiring the user to locate the problematic files. In folders with many files this can become a time consuming task.
This simple drop application was created to take those OSX "unfriendly" long names and truncate them, including any file extension to the 31 characters that OS9 accepts. In addition, to avoid name conflicts, the program will uniquely number each file or folder before the extension up to a maximum of 999.
Just drop the folder or the files on top of the application and the rest is handled automatically. You can then be assured of no random names being generated and all files uniquely named and numbered as well. File extensions are also respected.
If you have hundreds files, the process can take a bit of time and as long as the application is running (check your DOCK) it is still doing its job although you may have full control of your mouse.
If there are any errors, a log file will be created on your desktop detailing the problem.
Enhancements:
- Corrected behavior so that any folder or file name including the extension that is under 31 characters is untouched.
