Creating images for the Web 767
JPEG Optimizer Format
You can determine how an image appears as it is being loaded. You
can optimize the JPEG so that the image downloads one line at a time,
starting from the top.
You can choose to have large images displayed incrementally in several
passes; detail is added with each pass. This option allows the viewer to
see the image as it is being downloaded.
JPEG Optimizer Download Times
You can view the size of the compressed file and estimated download
times for four modem speeds.
Using the JPEG wizard
You can open the JPEG wizard from the JPEG Optimizer dialog box.
This wizard guides you through the steps of optimizing a JPEG file.
