EPUB Images options

The Images section of the Digital Editions Export Options dialog box includes the following options. From the Image
Conversion menu, determine how images are exported to HTML.

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 top and bottom padding.

Insert Page Break

Check to insert page breaks with images. Page breaks can be inserted Before Image, After Image, or

Before and After Image.

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
