Question about posting pictures.

Yes, this is very interesting,

I've always wondered why some digital photos seem to take eons to download, heck, I can wash and wax the car in the amount of time it takes for me to view a set of pictures.

A general rule of thumb: photographic images - save in JPG. Logos and solid color shapes - save in GIF, and remember, you don't need to set the dpi to more that 72, unless you need to print it.

Also, the Save For web removes a lot of extraneous meta data that isn't used for web display.

PNGs are not new and are not recommended for images viewed online hehe if it is an image for the web, save as a jpg

PNGs are sometimes used when someone wants a high-color image with transparency. GIFs only support a small number of colors, JPGs support much more colors but do not support transparency. PNG combines both worlds but some browsers are still working on compatibility with PNGs (for example, Internet Explorer currently does NOT support transparency in PNGs).

GIFs are used for animations also. All those cute animated avatars and siggies you see are saved as GIFs
