Optimize To Size Lets you specify a size, in kilobytes, for the image. For 8-bpc images, the wizard attempts to achieve
the requested file size by adjusting the number of colors or dithering.
Saved settings
Dreamweaver provides several option settings for your convenience. Depending on the saved settings you choose, the
file-type-specific image options described above may change.
GIF Web 216 Forces all colors to web-safe colors. The color palette contains up to 216 colors.
GIF Websnap 256 Converts web-unsafe colors to their closest web-safe color. The color palette contains up to a
maximum of 256 colors.
GIF Websnap 128 Converts web-unsafe colors to their closest web-safe color. The color palette contains up to 128
colors.
GIF Adaptive 256 A color palette that contains only the actual colors used in the graphic. The color palette contains
up to a maximum of 256 colors.
JPEG - Better Quality Sets quality to 80 and smoothing to 0, resulting in a high-quality but larger graphic.
JPEG - Smaller File Sets quality to 60 and smoothing to 2, resulting in a graphic less than half the size of a Better Quality
JPEG but with reduced quality.
(Optional) Change the image’s scale or export area options on the File tab
1 Select the File tab.
2 Shrink or expand the image in one of the following ways:
• Specify a scale percentage.
• Enter absolute pixel values for width or height.
3 Select Constrain to maintain the image’s original proportions as you rescale it.
4 Change the shape of the placed image by choosing the Export Area option and doing one of the following:
• Drag the dotted border around the previewed image as needed. You can drag the image within the borders to
move hidden areas into view.
• Enter pixel coordinates for the image’s boundaries.
(Optional) Preview and adjust images in the Preview panel
1 In the Image Preview dialog box, select the Preview option if you want to see what the image looks like with your
settings. If performance is an issue, you may want to deselect this option.
2 Select one of the saved color palette settings from the Saved Settings pop-up menu if you want to use a preset set
of options.
3 If your image is larger than the preview area, use the pointer tool to grab the previewed image and pan it to see
different parts.
4 Use the crop tool to reduce the image’s size. You may need to first zoom out to see the entire image.
5 Choose a value from the Zoom pop-up menu to expand or reduce your view of the previewed image. You can also
choose the Zoom tool and click to zoom in; Alt-click (Windows) or Option-click (Macintosh) to zoom out.
6 You can preview two or four different optimizations by clicking the 2-up or 4-up button at the bottom of the
preview panel and choosing different color palettes for each pane.
Note: The animation controls in the Image Preview dialog box are always disabled for Photoshop images.
