Hiya.

I would imagine that any setting that is not progressive would ensure that the pic downloads completely before showing. This does not seem to be the case.

I find that pics that download bit by bit visually lose something of an impact on the viewer. So how do you save a picture so that the picture downloads completely before showing i.e. in Photoshop?

This isn't really a function of the image, but is a function of html. In normal html, a page won't display, at least in Netscape, until the entire image is downloaded if the user has not set height= and width= in the img tag. Newer Internet Explorers will display the rest of the page, and when the image finishes downloading, display it and reorganize the page for the image.
The key bit of info is that if height and width are not defined, then the image doesn't download like you're talking about.

Here's the annoying part, regarding this board- the UBB code doesn't require that you give it height and width in pixels for the image to do this on the page. That makes me think it's using PHP to get the image info, and I don't know of any way to keep it from doing that.

If everyone has a fast enough internet connection, images will load instanteously anyway
