What File Type For Website Pictures?

I'm setting up a web page for my inworld store on a non-LL or Second Life related site. What's the best file type to post images for quicker downloads? I used PNG and the page loads slower than I'd like. Should I be using JPG or what?

Yeah jpg or gif usually load faster.

jpeg by far over anything else, or, if it's drawn material with alot of the same color, .gif is ok as well, this isn't anything special for SL, it's pretty standard for the web. Are you refering to the built-in browser? I really don't use, or really know many who do use the built in one. It's constrained to the tiny window and is a pretty basic browser at best.

JPEG is best for any image with a wide range of colour and tone such as a photograph or a painting. Use GIF or PNG for graphics like logos or drawings or UI buttons and dooberries, for example - anything that has a limited colour range and certainly anything composed of areas of flat colour.

As far as I can tell, the main advantage of PNG over GIF is that PNG images on a transparent background do not need to have a matte of anti-aliased colour to help them blend smoothly with the background whereas GIF images do. So the same transparent PNG may be used over and over on any background colour whereas a new GIF would have to be generated with a complementary matte to blend it everytime the background colour is changed.

I believe that PNG is also superior to GIF in terms of file size and colour reproduction but that might just be a subjective opinion. I do know that the main disadvantage of PNG used to be that it was not well supported by some browsers and, as far as I recall, Internet Explorer 5.0 and earlier versions was the most prominent offender in this respect. I think this changed with IE 6.0 but I can't be sure: I never use IE unless I'm testing a web page and I gave that up a few years back. It's a crap browser. Really crappy. Awful.
