Images have pixels per inch, printers do dots per inch.
You don’t need to do anything until an image is destined for output (Web or print).
You can then batch process the ones you have selected for print or web accordingly.
"Dr Brown’s Image Processor" is shipped with CS3 but you can download it for CS2 which, if I recall correctly, didn’t have it.
Thank you so much John for your correction. I meant PPI. Does your solution apply to PPI? Bringing the pix in at 300 ppi would really help because I then have to crop them to specific dimensions.

Images are made of pixels. ppi has nothing to do with the characteristics of an image file. The ppi is only a suggested setting if placed in the metadata of an image file. You can print your image at any size you want regardless of the ppi embedded in the file. Some printers will assume you want to use the embedded ppi setting but again this can be overridden.
So, Printed images have ppi. (image files do not, until they are printed)
So ask yourself, why are you trying to set the default ppi (you say dpi) of the image files? What are you going to use this metadata information for. Normally I just ignore this ppi metadata since it really does not mean anything, other than possibly the physical size you meant to print your image, but again it can be overridden at the time of printing.
Can’t you crop to specific pixel dimensions?
Thank you Ed……I CAN crop to specific pixel Dimensions but to give an example….I have to have the final image cropped a 10" (3008 pixels)x 6"(2000 pixels) at 300ppi…if I can bring in the photos at 300ppi then I really only have to crop them….and the job becomes somewhat simpler and easier to do.
Unless it can be Scripted (ask on the Photoshop Scripting Forum) I think the Action is the only way to go.
I have the same question as Jacqueline. When I transfer/save files from one camera (taken at SHQ 2288 x 1712 pixels) they come into PhotoShop CS2 at 72ppi. When I bring photos in from a different cheaper camera (taken at 1600 x 1200 pixels) they come in at 144 ppi.
I often send photos to publishers that require 300 dpi images. I understand that ppi and dpi are different and what the difference is. But, I am having trouble understanding how to get my photos into PhotoShop at higher resolution than 72ppi. And then what ppi results in 300 dpi?
Thank you,

the 72ppi one is probably coming in untagged. the 144 one probably has a resolution tag on it. use image> image size and set it to the desired ppi (300), and UNcheck the resample checkbox.
all that number is is a bit of information to tell a printer how close to put the dots. as long as you leave the resample box unchecked, you’re not changing the image at all, just a bit of data that’s associated with the image.
