Hi guys,
Q: I have 275 images, some at 300dpi some at 72dpi. I need to differentiate and label them correctly.
Now, does anyone have either an AppleScript or a Photoshop Batch Action that would make a report with the resolution? How should I go about this?
Thanks in advance

The images don't inherently have any resolution..thats just metadata added to the file.
All they reaaly have is x by y dimensions and a color depth.
Assuming they are all the same pixel dimensions, you could just sort by file size.Or you could use something like iView MediaPro to read any of the data (or embedded data such as the 'assigned' DPI), from the whole set and generate a text listing of the set...

the images vary in size, which makes it difficult to spot using file sizes. I need somethign that would generate some kind of report with the file name and the photoshop image resolution ...
hopefully, someone has made some kind of engine for this.
there must be a way of getting this info without having to purchase software.
I hope.

What do you want to do with the report? (whats the final aim here?)
- ribit0
Why not just batch process them all to 300dpi?(don't resample)
The image data is not changed at all in doing this. Only the assigned DPI (and therefore the assigned cm or inch dimensions) is changed. It's all metadata.
Is this useful? (It all depends what you are trying to achieve in the end)

ribit,
thanks for your help so far. i understand what you're saying, however, the bottom line is my prod. manager still wants to see this report, with all 275 file names and their current print resolution ...
have you ever heard of such report?
- ribit0
nope.. what do you do with it when you have it?
Seems sort of useless to print this out... more useful might be a way to sort/separate or process certain images? but we have no idea what you are up to...

open each image, look at dpi, write down.
i think that is the best you are gonna get.

try something like imagewalker for pc it has loads for ways of looking at files.
- ribit0
Theres a lot of faster ways than writing it down manually...
You can get a free version of iView... http://www.iview-multimedia.com

it seems useless, yes. but that's what she wants. i guess she want's to show the author (it's for an architecture book) which pictures we need to rescan.
i'm afraid i will have to go in, open each 275 images and record the resolution ... that's sucha mindless task, i'm positive that there must be something out there that will help out.

how bout looking at the file size? if it's a 20mb+ files.. chances are that it's at 300.
- ribit0
And remember the assigned DPI isnt going to tell you much on it's own... what if its 300dpi but the dimensions are only 20pixels by 20 pixels?
It's the dimension in pixels that counts. It's the only true measure of the size/quality of image that you have to work with. Everything else is a variable.
We only ever tell our contributors that we need a certain minimum dimension (say 1024x768pixels)... We never discuss DPI with them because it is totally irrelevant, and assumes you know something about the size of the physical image being scanned.

Montreal,
The images vary in sizes, there are a few that are less that 0.5 in by 0.5 in, and about 420K ... yet the dpi is set to 300.

Ribit,
I understand where your coming from, but I have to follow my prod. manager's direction and get some sort of report showing primarly the file name and it's res in dpi, the file size and the actual dimensions of the images are not as important as the DPI ...
that's why i'm just searching for anyhting to help me out here, because i would hate to waste half a day on that, since i have other jobs that would require that time.
i've just downloaded iView, and getting my hands dirty with that right now.
keep in touch

I see.. Then.. I can't help. sorry.
- ribit0
but looking at DPI in isolation is illogical.
(sorry if I sound like Spock)
- _d0
It's ok Spock,
I think iView is pretty much what I need, thank you so very much for the help ribit.
