COLETTE  I have the same problem. The most important is the lack of a customizable size, so that any user could define the exact dimensions for the loaded photos.

JAZZYGUY  Dunno! Using 10.5.8 on a 12"G4 Powerbook.I chose 6 .jpgs and used ratio 50% it didn't resize anything. I tried 25% no dice! I finally used Quickview's contextual menu and resized them all.You guys are raving about this app how come it didn't work for me?

FREDDUCKER  To me it's really the best but be careful when you resize using the "Width and Height" option since it might squeeze your pictures to resize them. You should never overwrite or delete without checking the results anyways.

RORO01  THE BEST FREE BATCH RESIZER

Many thanks to the developer for fixing the problem I mentioned below. I've tried all the application's functions using 200 photos and all work fine. The speed is amazing. Although more features would be welcome - as I wrote below - it is obvious from the application's name that they would be "extras".

LA SEPIA  Still has big bugs. have lost many photos.

not recommended.

FOULGER  How nice it would be if the authors of Resizeit & Resizemall would have a preference for measurement, imperial and metric as well as pixel size.  
(Version 2.0.1)

RORO01  It would be great if the developer could add two features:

1. Ability to draw borders like PicMark.

2. The "make sequential" and "Add Text" features of

the Automator action "Rename Finder Items".

MACOSXPC.COM  I think Resize 'Em All (http://www.macupdate.com/info.php/id/25531/resize-%27em-all) still the best!  
(Version 2.0)

RORO01  MAGIC

Thank you ever so much. I was waiting for such an application. The only reason I didn't give it five stars is because if you tick "Overwrite Files" the application quits. In reply to the previous posting - it does batch processing. Just select multiple images.

HENRIKTEKNIK  Nice app. But it would be awesome if it could flip/rotate images too. Batch processing would be nice as well, but not paramount.

Thanks!
