I mainly use Picture It!, but that didn't have anything in it.

Assuming it is a JPG (most online and camera pictures are...)
You can either resize it (less resolution, fewer pixels) or change the "compression ratio". However, low quality compression can make your picture look like a parquet floor.
Resizing means fewer pixels. It will have less resolution; but then, if it's only for monitors - well, a really sharp monitor is about 1280x1024 or about 1.2Mpixels. Most camera photos are 3 to 8 Mpixels; makes the picture way too big for monitors, but nice and sharp for printing. A picture on a web site that fills 1/4 of your monitor is probably less than VGA quality (640x480, 0.5Mpixels)
JPG is (technical details here!!) a compression technique where the picture is chopped into 8x8 squares and then a math trick is used to reduce the number of numbers needed to describe what's in there. They use a trick call "Fast Fourier Transformation". The more detailed the result, the bigger the file. JPG "Save AS" under "Details" can give a number from 1 to 10 or 12. below 8, quality can deteriorate.
Experiment with size or quality, but use "SAVE AS" and save with a new name, so you keep your original in case you want to start over.
You can do either from Paint or Photoshop. See the other posts for instructions.

Open the picture in Paint (Start > All Programs > Accessories > Paint)
Go under Image and select Stretch/Skrew
Change the horizontal and vertical stretch to the size you want
Resave the picture (use a different name is you do not want to overwrite the original picutre)
Note: Change the pictures size will reduce the clarity of the picture.

I don't know Picture it!
But the answer is to compress it.
Typically this just means saving it as a jpg file. For example if your camera gives you a file as RAW the file size might be 7mb. Saving it as a jpg will compress it down ... to maybe 500k.
Also, resolution is part of it. If your image if for the computer or internet 72 dpi is perfect. For printing ... maybe 300 dpi.
Check the settings on your camera -- you can often set them with jpg and 72 dpi resolution before it ever gets to your computer.
Have fun!

What program do you use to upload your pictures?
For example, I have HP Image Zone. There is a choice in "edit" to change the file size. In fact, it states that you can shrink the file to accommodate a suitable size for an email attachment.
Check out your photo production software. Why not use a feature you paid for? ;-)

In order to change the file size, you will have to adjust either the physical image size or the resolution, or DPi.
I am not familiar with Picture It! as I use Photoshop.

The easiest way will be to open the image in photoshop and resave it as JPEG with the quality slider set to 'medium' or 'low' settings

You can resize it, or change from whatever format you use to something compressed like a jpeg.
