when you want to downsize a image file it offers two sizes - one
recommended for e-mail and one recommended for images for a web page.
Then, after selecting one of these, it offers a choice of decreasing it by
pixels or by percent of original. This is the part I am not sure about.
I'll try both and see if I can determine the difference, if any.

Shouldn't be any difference. Reducing a 3000X2000 image to a specified
1500X1000 pixels should give the exact same result as a request to reduce
the image by 50%, within the same program. Same resizing and resampling
algorhythms should be used to get there.


More advanced programs such as Photoshop and Paint Shop Pro give you a
choice of several reduction methods and optimizations. I use Irfan
view also, and it does a pretty crude job of resizing, and the
resulting file size is always much larger than those produced by more
sophisticated programs.

Irfanview is mostly useful as a quick viewer when you want to go
through a folder of photos. It's not really intended as an editor.

With Irfanview, you can make the file size as small as you want.
