I loaded Photoshop to a PC with Win 98, and
found out whenever I save any JPEG file,
it ends up being save as a .ART file!
Where did the original file come from?
It sounds like you have America Online on your computer. A .ART file is an America Online compressed image. When you use the America Online browser, it "speeds up" Web display by taking all the .GIF and .JPG images on the pages, compressing them using the proprietary .ART format, and sending those .ART images.
It makes Web pages look like crap; .ART is highly lossy. It also means that if you use the AOL browser to save a JPEG, you may look at the file and think it's a JPEG, but it's not. It's an AOL .ART file.
Photoshop does not save .ART format files. It saves .JPG files. It sounds like either something's wrong with your AOL installation, or somehow your Photoshop ..JPG files are being viewed using an AOL browser or converted by AOL to .ART files.
