Edit - please note this guide is also in the sites help section
Quite often you may have a batch of photographs where you would like them all to be the same (smaller) size. Not everyone has access to Photoshop so hopefully this should show you how to do it quickly and easily.
I realise there seems to be a lot of steps but it really only takes a few seconds to do once you are used to it 
First of all download and install Irfanview - a link is provided at the bottom of this page.
When you open Irfanview you should see something like this
Click on File
You shoudl now click on batch conversion - there are lots of options here but for now let's stick to the basics
We now need to set up the application for how we want our files resized
Click on advanced options and set advanced options
Set the options as shown above
You have now set up the application for batch processing. You now need to tell it what files to include
Navigate to the directory you want to use in the normal way
Add files as indicated above
You now need to say where you would like them save
Click on Browse and set your output directory. You can also click on 'use this directory as output if you want the files directory you have already selected
All the files should now be shown on the left, click 'start' to, err, start!
Hopefully this should help some people - note though if your images are in Adobe RBG you should convert them in Photoshop to SRGB so you'd be better using image processor in that application.
Let me know if I have missed anything

No worries mate.
If you have CS2 then there is an even easier way. Go to File, Scripts, Image Processor. That will batch convert a folder of images for you as well as converting the colour space if needed.

Is there anyway to resize images in terms of actual memory and not physical size, without drastically reducing the quality?

I suspect you mean files size(actual memory) and 1:1 display size. Most images displayed on here are jpegs which make use of a variant Mandelbrot fractal. It basically creates a list of recurring colour shifts. The more diverse detail the original image contains, the larger the compressed image, because the fewer recurring colour shifts and the longer the list of varying colour shifts. Therefore a picture of a Paisley pattern scarf will be quite large and that of a plain green wall very small.
It is a case of quarts and pint pots, things will only compress so far without visible loss of quality.

Yes in the batch convertion box click on the Option tab and it has a slide scale 1-100
Ps there is a newer version out than the one shown think its version 4.1 it has some upgrades and a different interface

It always makes me smile when I see the torture Windows users have to go through to do a simple job like resize a bunch of photos.
On Linux (or Mac, if you're in the know), you simply create a directory for the resized images (smallpics, in this case) and type:
convert *.jpg -resize 600 smallpics/img.jpg
The output images will be numbered img-01.jpg, img-02.jpg, etc.
If you want to retain the original names, you do this instead:
for f in *.jpg; do
convert $f -resize 600 smallpics/$f
done
This simply means that for every file which matches *.jpg, set 'f' to the filename and substitute it in the convert command for both the input and output file names.
Of course, resizing is only one of many processes you can perform. You could also add borders, sharpen, soften, crop, add text and many other things.
If this has whetted your appetite, I'll be launching a web site in the near future: www.linuxphotography.org, where this and the other free software we use as alternatives to Photoshop will be explained and discussed.
I've also just written a series of articles on this subject for Linux Format magazine.
If you'd like to know when the new site is up or have any questions about using Linux for photo post-processing and library management, I'd be happy to help.

For my two pennies then.
Best one ive found, and by far the quickest - as much as i hate them i love this little gem!
download and install, click on an image, or shift click to select multiple images.
Right click and there is a new menu option, 'resize pictures', it has some standard defaults or you can enter custom sizes. Takes a few seconds to do loads. Far quicker than an action in PS etc.

Direct link above - and suprisingly it was compatible with XP....

Lenscape..no torture in windows/Photoshop!! Go to the "action set" in CS3..open automate batch, select the source and recipient folders, hit "OK" and leave it to it....takes seconds!!
And those actions are..."Start new action", "open file", "image size, 450 pixel width", "72ppi output res", "save as, Jpeg (around 6 to 8 quality)" in selected folder, "close" ..!
How tricky is that??

How do you create a JPEG from a Tiff
I can do this
* JPEG’s saved at a high quality setting (i.e. Photoshop level 10 or above).
And this
* Alpha-numeric file names ending in .jpg.
And this
* RGB files, not single channel greyscale or CMYK.
But not this..
* Uncompressed file sizes of between 48MB and 200MB. This means you should make your JPEG file from an 8 bit TIFF file that is at least 48MB. Our maximum size for the uncompressed file is 200MB.
every time I convert a tiff (58mb) to jpeg it ends up at 9mb (irfanview) and it needs to be 48mb minimum No option to save as jpeg from tiff in photoshop.
Help....

Microsoft Office Picture Manager.
Using edit images-compress three size options but original image not saved so use on copies. (Web size on this is what my NM images are).
Batch resizing and renaming.
Resize incrementally also.
File- Export,more size options and original is saved but individual images

If you can't see the jpeg option in PS then the file is still in 16 bit. You need to covert to 8 bit (and for most uses SRGB) and then save as a JPEG.

I have used the above method before for resizing and converting from CR2... have tried again (following these instructions) and I get an error message telling me it can't load the images I choose...
any ideas?
