    Converts numbered lists into List Items, which are formatted in HTML using the

      Converts numbered lists into List Items, but assigns a attribute based on the paragraph’s current

      number in InDesign.

      Converts numbered lists into paragraphs that begin with the paragraph’s current number as text.

      Opens the EPUB in the default application selected for reading EPUB, if present.

      EPUB Image options

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

      Check to inherit the image object attributes from the layout.

      Choose 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 choose a ppi value for each object
      selected. Values include 72, 96, 150 (average for all eBook devices today), and 300.

      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.

      Specify the image alignment, left, center, right, and the space before and space after.

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

      Check to apply these settings to all anchored objects.

      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.

      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.

      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.
