I specifically used a quality level of 100 or 99 in the original comparisons above.
Using anything less will result in the loss of pixel information as you can see.

Anyway, I'm not trying to start an argument here, just giving a heads up to the people who don't know that there IS a difference between JPEG output on various applications.

"Athanlore: excellent demonstration :D"
hehe thanks

The ratio for the above are about the same across the board for any JPEG image output, considering the output quality level is within a percentage or two within each other, regardless if the background/scene is busy or not.

Resaved in Image Optimizer, Quality 99, MagiCompression 50%, Erica-ImageOptimizer1.jpg, 58,172 bytes.

Raw Poser render, JPEG Max Quality 100, Erica-Poser.jpg, 119,802 bytes.

I was going to post a similar thread in The MarketPlace Wishing Well, concerning the promo images, instead of the gallery.
I use both dial-up and cable depending where I am at the time. I sweep through the RMP and other stores, and purchase dozens of items at a time, needless to say this requires loading hundreds of bloated promo images.

"If you want to preserve 100% quality you only can save as BMP, PSD, PNG"
add .TIF in there.
