Most photo editing programs will allow you to change the file size.
This is done two ways from within the program. First you can (usually from a pull-down menu) change the pixel size. If you're posting on Ezone a width of 600 pixels is good. This is reduced from over 2000 pixels that I get with my digital camera right out of the camera. Next, when you save the file after reducing the size the program will ask you the quality of the saved file. If you choose "10" there won't be a reduction in quality, but the file size will remain large. Choosing "3" might get you to where you want to be.
There are probably loads of shareware programs available, but Paint Shop 7, fully functional, is available for a 30-day trial at:

I've been using MS Photo Editor without a problem for this.
Just open the file, and click on Image|ReSize
You can adjust according to pixels, inches, or centimeters, in numbers or percentage.

What I usually do is open MS Explorer, so I can see the file's details, and MS Photo Editor. I open the file, reduce size and save under a different name, then put MS Explorer on screen, hit F5 and check the file size.

I save under a different name because once the file is reduced, it will become fuzzy if you enlarge it again.

Hope this helps

I've tried most of the shareware and freewares and the best is totally free.

It's called Irfanview and it is small, lightweight and totally free image viewer and editor.

You can reduse the DPI to 72 and that will make the file size smaller.Photoshop can reduse the actual image size as well as do anything else you want but its $$$$

If you are reducing images to small size (avatars are a good example) the software you use is fairly critical. Bundled s/w like MS Photo Editor or MGI PhotoSuite will give poor results, anything else (I use Paint Shop Pro 7) will work much better by using far more sophisticated algorithms when deciding which pixels to drop and which to keep!

But for resizing down to (typically) 600 pixels max. width or height plus a bit of compression, most software will be OK.

BTW 100 Kb is still a bit big for posting inline pics, I normally aim to compress down to 30-50 Kb. This normally still gives good enough quality for viewing on screen.

E.g. this is 31 Kb:

I use a program called IrfanView that I got off http://www.winfiles.com.

There's only one way I know of to reduce the size of JPG files, and that's to reduce their resolution.

Which is why the pics in my avatar are so cobby looking.

I downloaded the trial Paint Shop Pro 7 and used it a little - but the trial period is over now.....so I have to decide to buy or look at something else. I want something that can do lines and simple curves as objects rather than just pixels and I couldn't make the curves work the way I wanted in PSPro 7.

I've owned PSP for years. Never bothered to pay to upgrade beyond v.5, but still prefer to use it over all the bundled photo-deluxe and such packges that come with new computers..

Yes, I ran the demo 'tour' of of Paint Shop Pro, downloaded the trial version, liked it a lot, bought it.

The current version includes loads of other stuff e.g. Animation Shop. My Avatar is a still photo of my own Mini IFO with the prop "cut out" into a new layer in PSP, then rotated & blurred slightly in Animation Shop to make the animated GIF.

I've never tried to do anything like that before, I'm no graphics expert but I found it reasonably straightforward and managed to work out how to do it all. Good fun!

The older versions of PSP often get given away with magazines, a UK one last month had a full version of PSP 4.4 (?) with it plus a cheap upgrade to the latest version if you liked it. Other software is also promoted the same way so keep an eye out.
