On the web images should be uploaded at their actual size (100%)in RGB colour mode, not sized-down or sized-up, this is the bestpractice for maximum quality imagery.
If you have to re-size an image and you don't have photo editingsoftware it's always best to size-down an image rather than size-up(you can do this in the IGLOOeditor).
The web works using pixels, images online are just small squaresof colour that when seen at a distance (and at 100%) become a sharpclear image. When you increase or decrease the size of an imagebeyond its actual size the pixels have to compensate for missingdata and therefore can look out of focus or broken down.
