Does Photoshop allow batch processing of files (pictures)?

For example, if I have a collection of photos of relatively high resolution
in JPEG format, can I set Photoshop to resize (ie decrease the resolution)
on the whole set with a single command, rather than have to do each photo
individually?

If not with Photoshop, are there other photo applications that can do this ?

TIA,

Mark.

Yes. In Photoshop look up Actions and Automate in Help or the manual or
on the web. What you do basically is record and action of doing it on
one file and run it as a batch from File>Automate.

Irfanview will do this also as will XnView and many more for both
Windows and Mac.

It would be insane if the the best professional imaging program on earth
could not batch.  It sure can. I've done as many as 3000 images before
lunch routinely using batch (and alternately, droplets.)

If you have Photoshop, see "help automate".

That is the first mention of droplets I have seen in a long while. If I were
doing a lot of files I would not use an action...you still have to press the
action's button constantly. I would make a droplet. Then just drag the files
over it.

Droplets are cool but they're not editable. I don't see the difference
between dragging and dropping and pushing a button. If you put all your
files in a folder you can Batch them with an action and don't have to
push any buttons.

One virtue of Droplets is calling them from the WindoZe command line. You
can then use the job scheduler to run certain jobs unattended, for example
a variety of long jobs in sequence over a weekend. You can also write a
script application to process files using the droplet. Imagine a job where
you have PS on a network computer and a 'watch folder' application; when
the app finds the folder contents have changed, it calls the droplet to
process the contents (and move them, etc when done.) I haven't explored
OS-X in this regard, but I'd terribly surprised if it didn't work there as
well.

I've posted the How-To on this a couple times in the past year or two.

Maybe I am learning something here. So...the editing is not an issue. You
edit the action and make another droplet. That is not very time
consuming....5 secs?

I have never tried to batch a folder....but what if, as I do, there is a
folder of my original jpgs from the camera. With them are the psd from the
editing. Now...I want to change them...either to jpg for the dotphoto.com to
be printed...or for publishing in my magazine....from explorer I can drag
files to the droplet...I don't see how that could be easier with an action.
Even if I could do the whole folder...I don't want to.

Please enlighten...am I missing some capability that PS offers?

Well, you would have to have a folder with only the files you want to
process. All depends on how you work I guess.

You realize that Adobe warns very strongly against running Photoshop
across a network or opening/saving files across a network?

I am not running the executable across a network. The files are on the
same machine that PS occupies and saves them on the same machine. I am not
aware of Adobe's particular position on using their software from the
command-line. If it is verboten, then perhaps Adobe will make the effort
to tell me: until then, I will continue as-is. (And if they do protest, I
will certainly share the memos with the group.)

You would think that if Adobe didn't want PS to run from the command line,
they would have obviated simple foreign entry into the executable, but
they don't so it's got to be okay, or perhaps just something they have to
tolerate as long as WindoZe prevails.
