determining image dimensions/resizing precisely

I have imported a number of JPEG images and then resized them using
Transform within their layers. Visually, they now appear as rectangular
boxes within beveled borders. However, since I sized them by eye, I can
tell they do not all have exactly the same x/y dimensions.

I there a way I can settle on one of the images as a model, read its
x/y dimensions, and then resize the others to match?

Sure. See File - Automate - Fit Image
It remembers the last dimensions you used.
You can also use it in 'batch' to do as many as you like at once.
Try automating from the file browser (if you have CS).

I have imported a number of JPEG images and then resized them using[color=darkred]

uh JPG format does not have layers
this seems like a very weird way to do resizing. Just use Image>size? why
use transform? Transform is to manipulate parts of an image not to resize
the whole picture.

if you need to resize a bunch of images for web usage try using "save for
web" choose the image size in that palette.
If you have a bunch to do, record and action and run it on a folder of
images using File>Automate

Thanks, but I'm not getting that to work: these are images I imported
several days ago, and I'd rather not have to remove and re-import them.
I highlight one of the layers in the palette (if I try to select the
image directly, I get a "Could not select a layer because the point you
clicked on is not inside the vector mask of a visible layer"), do File
- Automate -Fit Image, and I get a box that says width is 576 and
height is 359, but I don't see a way to directly modify these
dimensions.

Is there a way to do that?

First, I presume you wish to change the dimensions of the entire image. Am I
correct? If I am, then Yes sir, there is a way to change the Fit Image size.
Just put your cursor into the box and change the dimensions to the maximum
you will accept in each dimension.

However, if you aren't forcing every image to exactly the same size, then it
might be easier to use "image size". That will reduce the entire image, all
layers in acccord. You can then save it as a different name if you wish to
keep the originals intact. You can use an 'action' to automate it. If this
sounds daunting, perhaps we can step you through the first one. Once you see
how easily it is done, and how fast it is, I think it will change the way
you work.

Thanks, but I think the mist is clearing. What frustrated me was that
Image Size only reflects the entire image (I see Link symbol), not the
five or six small image each in its own layer that I used to build it.
I understand now that I should settle on a size for the smaller images
and set them with Image Size as I import each. Thanks for your patience.

Thanks for this tip. I had never noticed Fit Image - might be useful in the
future.

Kevin,

It looks like you've gotten some very good suggestions and thoughts on your
project. One caveat, that I'd like to add, is to always use the pixel
dimensions for all of your resizing needs. If one uses inches, or other
dimensions, except for pixels, there is a chance of getting it very close, but
off by a pixel. I've faced this with images that had masks in the Alpha
Channel, and then having a 1 pixel edge, where my "inches" rounded off by 1.
Not a biggie, but once you have to "repair" a dozen images, one remembers.
