CentOS - May 2009 - OT: Photo Editor to reduce 272 photos to VGA at once

I returned from Bogot? and have a Folder with 272 photos that total
419.9 MB. I would like to email them to several people who were there
for the concerts I attended. I have Picasa, gThumb (not really an
Editor but I believe it can reduce the quality of photos) and The GIMP
installed. Is there a way I can have a photo editor reduce all of them
to VGA size, without doing that 272 times? The people who will receive
them  are using M$ Windoze.  Also, they are in a folder and it doesn't
seem possible to attach a folder in gmail. A good way to zip them up
in one file that can be unzipped on Windoze boxes? TIA!

P.S.
I met people there who participate in the forum for my favorite
singer. I suspect it would be equally interesting, to meet many of the
people who participate in this Mailing List.

ImageMagick's "convert" utility can do that.. Don't have the
syntax
handy, but it's fairly trivial.
Just work on a copy first :D

Maybe something like:

convert -resize 640x480 *.jpg concert.pdf

Might require a lot of RAM...

You can do this with ImageMagick's tools.

mkdir shrunk
for in in *.jpg ; do convert $i -resize 640x480 shrunk/$i ; done
change 640x480 to whatever size you want.

Use convert from the ImageMagick package (convert -resize).

yum install zip (if it isn't installed already).

Why not upload to one of the online photo sharing sites like flikr or 
google's picasa web albums, send a link and let the recipients worry 
about whether or how to download copies?

the ImageMagick tool you probably want to use is called 'convert'.

as for compressing the folder of images, `yum install zip; man zip`.

why not post them on a website like picasaweb.google.com (since you 
mentioned picasa) and then just email the URL ?

picasaweb will autoscale them to a variety of sizes and show them to the 
user sized to his screen.  for instance, my pictures of an astronomy 
campout I went to last fall...

Thank you, to everyone who responded and for all of the ideas!
ImageMagick seems to be one way to go. Posting them to Picasa online,
the other way. I agree that emailing them to everyone wastes a lot of
bandwidth. I must make them available to the Webmaster of the official
web site and one of the chorus singers (a serious amateur
photographer) has a blog and he wants them. And now I have people who
participate in the forum who want them to. If I can get them posted on
Picasa for free and they can download any of them they like, that's
the best way probably and the easiest for me. I was standing about one
meter from the stage, so I have some very good photos, along with some
bad ones. Thanks again! I will check out how to get them uploaded to
Google's Picasa, since I have Picasa installed.
