    I need to do a lot of image rezing at my job and am looking for software to help me do that. I actually use a PC at work, so if you know PC programs that will help, that would be even better. The photos I'm working on are sorted into various folders. I've found programs (such as iredsoft image resizer) that will allow me to import a folder and resize the all the photos in that folder.

    But, I'd really like to have some additional functionality, such as being able to select a group of folders to batch resize all of their images and have them saved back to their original folders.

    Another feature I've had a hard time finding is to be have the software recognize when the photo is already small enough. I need to keep the max size to around 1200x1200 pixels. Most of the photos I use are bigger than this, so there's no problem having it set everything to 1200 pixels wide. But sometimes they are smaller and most programs seem that they would blow up the image to that size, which isn't what I want to happen.

    Like I said, I'm primarily looking for a PC solution, but if a great mac solution is available, maybe I can bring the photos home somehow and work on them from my mac (whihc runs OS 9 by the way)

    Any help always appreciated.

    Well, there is always Photoshop actions. Write your actions and go for it.

    However, if you want the ultimate software, use Equilibrium DeBabelizer

    DeBabelizer's website

    The price for a new version is $499 and it is for the Mac or PC. I've used this program for about 7 years and I've had no problems with it.

    Hands down the best batching tool. Of course, that is all it does.:p

    Sounds good, but there's no way I'll get something that expensive approved. Thanks though.

    I found a program off of VersionTracker called iPhotoBatch.
    I don't know how much it cost :)D) but check it out.

    If you don't mind the command line try installing the ImageMagick toolset. You can then use the mogrify tool to perform a whole lot of transforms, including resizing.

    i.e. /usr/local/bin/mogrify -resize 800x600 *.jpg would resize all jpegs in the current directory to 800x600. As this is on the command line you can script (or even AppleScript it).

    If you want to know more about this then follow these links.

    By default, the image format of `file' is determined by its magic
    number. To specify a particular image format, precede the filename
    with an image format name and a colon (i.e. ps:image) or specify the
    image type as the filename suffix (i.e. Specify 'file' as
    '-' for standard input or output.

    if you know your way around PHP you could quite easily create a PHP script to do it for you using GDlib, but the resizing in PHP is pretty nasty; i wrote a script for an online image gallery that'll handle batch uploads in gzip'd files that you could use?

    i'm pretty sure there are some applescript droplets that allow you to do this to a single file or a whole folder of files. also, 10.3 will include a new library called vImage that takes care of things like this, allowing you to do nifty things like create a folder that will resize/modify every image dropped into it.

    GraphicConverter has some pretty good batch controls and I'm pretty sure it's cheaper than DeBabelizer.
