Image options
Copy Images
Specify how images are exported to HTML.
Original
Exports the original image to the “
all other options are dimmed.
Optimized
Lets you change settings to determine how the image is exported.
Link To Server Path
Rather than exporting images to a subfolder, this option lets you enter a local URL (such as
“images/”) that appears in front of the image file. In the HTML code, the link attribute displays the path and extension
you specify. This option is especially effective when you’re converting images to web-compatible images yourself.
Preserve Appearance from Layout
Check to inherit the image object attributes from the layout.
Resolution (ppi)
Specify the resolution of the images in pixels per inch (ppi). While operating systems have
standardized on either 72 ppi or 96 ppi, mobile devices range from 132 ppi (iPad), to 172 ppi (Sony Reader), to over
300 ppi (iPhone 4). You can specify a ppi value for each object selected. Values include 72, 96, 150 (average for all ebook
devices today), and 300.
Image Size
Specify if image size must remain fixed or resized relative to the page. Relative to Page Size sets a relative
percentage value based on the size of the image relative to the InDesign page width. This option causes the images to
rescale proportionally, relative to the width of the reading area.
Image Alignment and Spacing
Specify the image alignment, left, center, right, and the space before and space after.
Settings Apply to Anchored Objects
Check to apply these settings to all anchored objects.
Image Conversion
Lets you choose whether the optimized images in your document are converted to GIF, JPEG, or
PNG. Choose Automatic to let InDesign decide which format to use in each instance. Choosing PNG disables the image
compression settings.; use PNG for lossless images or for images that include transparency.
GIF Options (Palette)
Lets you control how InDesign handles colors when optimizing GIF files. The GIF format uses a
limited color palette, which cannot exceed 256 colors.
Choose Adaptive to create a palette using a representative sample of colors in the graphic without any dithering (mixing
of small spots of colors to simulate additional colors). Choose Web to create a palette of web-safe colors that are a subset
of Windows and Mac OS system colors. Choose System (Win) or System (Mac) to create a palette using the built-in
system color palette. This choice may cause unexpected results.
Select Interlace to load the images progressively by filling in missing lines. If this option is not selected, an image looks
fuzzy and gradually becomes clear as the image reaches full resolution.
JPEG Options (Image Quality)
Determines the trade-off between compression (for smaller file sizes) and image quality
for each JPEG image created. Low produces the smallest file and lowest image quality.
JPEG Options (Format Method)
Determines how quickly JPEG graphics display when the file containing the image is
opened on the web. Choose Progressive to make the JPEG images display gradually and in increasing detail as they are
downloaded. (Files created with this option are slightly larger and require more RAM for viewing.) Choose Baseline to
make each JPEG file display only after it has been completely downloaded; a placeholder appears in its place until the
file displays.
Ignore Object Conversion Settings
Ignores Object Export Options applied on individual images. See
Advanced options
