John, it's not so much about resizing as it is about increasing the compression slightly (photoshop slider at quality 8 is still very good), and decreasing the DPI; it comes out of your camera at a DPI that's fantastic for making actual prints, but unnecessarily huge when it comes to web pictures. I know my copy of PS elements has a 'save for web' option, maybe CS does as well. Should take care of that on its own.

Yep this I know. It does have the "save for web" feature, and I used that,
but I choose the 100% quality. Mine is set on 1-100 not 1-10, and 80% on
mine do look fine..but again like I said I was feeling the need to kick it up
to full quality...here is a smaller (in file size) version just so you guys
know that I CAN do i if I wanted to I just did not want to!!

Here is a good method to compress images for the web. It is the very best I have ever found. (Yes, I know there are little programs that do this, but in a side by side comparision this method produces much better results -- it is just slower.)

If you are resizing an image never reduce it by more than half. (For instance if your image is 1200 x 800 and you are targeting 300 pixels wide only reduce it on the first pass to 600 x 400)

Then use an unsharpen filter with the parameters set at:

Sharpen Amount = 100
Pixel radius = .6
Threshold = 0

Then reduce it again (by no mre than half)

Unsharpen it again

Each time you reduce the size unsharpen it.

As an added kicker run a gaussian blur feature on it with the parameter set at .2 before the final save.

That will give you very clear crisp images that are sized nicely for the web. It is especially good if you need to preserve detail (such as type)Brock Poling38743.8672569444

John,

No problem if you want a critique.
