Hello Every,
I am checking out a canon digital camera I'll be using with my summer school
kids. The problem is that each photo averages in size from 1.5 to 5 megapixal.
With my home computer (Windows XP), I'd use Roxio Photosuite which would
compress the photos to less than 100 kilobytes in size. But now I have
Vista.... Any suggestions for cheap/free compression software--Picasa???
Thanks,

On XP I find the Image Resizer Powertoy to be very useful for quickly resizing
batches of images (if you haven't tried it yet, check it out). Unfortunately
this does not yet seem to be available for Vista. However, I just found this
info on the web which you might find helpful as it seems like a similar tool to
the XP Powertoy mentioned above:

You can also bring your pictures into Windows Paint and shrink them using the
Image > Resize/Skew and then shrink them to 25%.

However, I believe you are confusing resolution with compression. JPG's are
already compressed. You are taking your pictures in a high resolution mode.
Your camera has settings to take them in a lower resolution. Look for one that
says 640x480 and that will give you photos suitable for the web.

Photoshop Elements 6 - Educational price is very reasonable, like around
$60-75. You can batch convert folders of photos to any resolution you would
like.

Check out their new Photoshop Express, an online version of PhotoShop/Photoshop
Elements, and it's free.

Do you mean that you desire to further compress a file that is already JPEG?
Doing so may well-will most likely-cost you a lot of resolution.

You can compress your images right on the camera, you don't need to move them
to the computer before doing so. All digital cameras I have seen (and I know
Cannons pretty well) let you set the compression level on the camera. They
also let you set the resolution (image size). For most school uses, I would
set a low resolution (like 800 x 600) and a high compression (like 30%) this
will take your file size way down and allow you to store many hundred
pictures on your camera. You only need high resolution if you are going to be
printing large format pictures.

I hope this answers your questions.

I'm sure there is plenty of compression software that you can get, but you
might start with your camera. Many digital cameras have settings that allow you
to adjust the size of the pictures taken.

There are free softwares that will do what you need.

Irfanview and Gimp are good choices. Picnik is an on line editing service that
will also al;oow you to resize.

They all work

Thanks to everybody who responded to my request--I learned a lot. However, I
found the Export function of Picasa is just what I need. Also, Picasa
automatically resize photos being transferred to a web album....
Kind Regards,

You also want higher resolution if you want to significantly crop the photo.
Say you have a photo with three students, and you want to crop it so just one
of the students is in the final photo. If you are cutting it down that much,
you may be using just 1/4 of the original pixels (or less).
