[mike]

Hello knowledgeable ones!
My scanner epson 1260 with tranny adaptor, allows me to save as jpeg- progresive or just a jpeg, can any one tell me what the difference is here and also point me in the right direction to what I should be saving as?
I hope to be submitting some of my work in the not to distance future.
Thanks
Mike

Mike here is some info about Progressive JPEGs


Progressive JPEGs are similar to Interlaced Gifs and are loaded in the browser in a series of passes. First a 'blurred' image is displayed, then as more information flows in, the clarity increases. Most image editing and manipulating programs let you indicate the number of passes you want to have in the image.

In contrast to GIF, Progressive Jpgs are slightly smaller than plain jpg files. You'll use JPG mostly for photographs and these tend to be large in size (both in physical dimensions and file size). The advantage offered to the visitor is that he or she atleast gets an idea of the image. Hence, I recommend using progressive JPGs always.

The only disadvantage in using Progressive JPGs is that they require more processing power by the client machine and the browser. However, in these days of high computing power and continuing improvements in browser software, this aspect can be safely ignored.
