Photo resizing in bulk with folders?

Hi, does anyone know of an effective and simple drag and drop photo resizing program that will do pics in bulk? Had a quick search of the archives, but I'm after something that will reduce a 1MB pic down to say 100K - 150K image suitable for e-mailing.

I currently use Photoshop and I've set up a macro to make things quicker, but there must be something simpler around.

What I want to do is take a whole pile of high res images, download them to my PC and have the ability to simply select all the pics at once and drag them to into a program that keeps the originals at hi-res, but also creates low-res duplicates for e-mailing. ie: the best of both worlds.

I also want this program to identify the lo res images by keeping the original title, but adding 'LR' (lo-res) to the end. I'd like all of these lo res files to automatically be sent to a new subfolder created in the source folder eg: I download 10 hi res pics and title them "Collie 1", "Collie 2" etc. I want my main 'Collie' folder to end up with the originals AND a sub folder of 150KB images with 'Collie 1 LR', 'Collie 2 LR' etc as their titles to e-mail to friends.

Any ideas?

Thanks in advance.
