    I've got several thousand photo's that are all captured in a variety of resolutions, ranging from 1024x768 all the way up to 12MP.

    These have all been categorized and each now resides in a named folder representing the category.

    I wish to resize everything to 1024x768 JPEG's. Is there a batch resizing app that will let me do this in one fell swoop or do I need to go into every single folder, open everything and then do it manually?

    I've been searching via Google and this forum, and thus far, everything that has been recommended is only for much older versions of OSX. iResize for example...doesn't work on my Mac (Lion).

    You should try Automator - it can recursively scan folders for jpegs, and there're some photo-related actions for resizing.

    Best of all: it's on your Mac already!

    ps., Think twice (though I suppose you'll do) before deleting the original, because the pixels you loose will never come back...

    Yeah, I'm working off a backup of the full directory. Objective is to put every picture in the library onto a 64g iPad for viewing. The folders themselves are over 100Gigs, but if I drop everything down to 1024x768, they should all fit on there with plenty of room to spare.

    Unfortunately, when I tried using Preview's Resize function, its only works if all the original pictures are the same size/orientation to begin with. Thanks for your advice on automator...I forgot that it had that ability.

    Try EasyBatchPhoto .....

    I haven't tried dropping a folder (much less nested folders!) but perhaps it will do what you need. At the worst you will need to open each folder, then "select all", then drag and drop. You can create a preset that will overwrite the originals, I'm pretty sure.

    Automator has, I believe, a "watch me" feature. So once the preset is created you could have automator watch you open the folder, select all, then DnD the images onto EasyBatchPhoto. Then all you have to do is select the folder and invoke the script.

    One caution with EBP.... the interface is not entirely intuitive, so spend some time fine-tuning the preset on a limited number of folders before letting loose on the full collection. EBP will probably work for you, but it may take some work to find where the feature you need is.

    I keep using it because it is a fairly powerful batch processor.
