A script for Adobe InDesign to export images to web-friendly formats.

1. open InDesign Scripts panel
2. right-click on folder entitled "User" and select "Reveal in Explorer/Finder"
3. copy image-export.jsx to this folder

• image-export.jsx needs at least Adobe InDesign Version 8.0 (CS6)
• image-export_pre-cs6.jsx works with Adobe InDesign Version 7.0 (CS5) but supports only JPG output. I've tested it on CS5 but it may work on CS4 as well.

• adjusted size, bleed, transparency and orientation settings are applied and automatically exported (please note that this works not with locked layers)
• for multiple linked images, every instance is stored as separate image with a unique name and its settings
• select output directory, compression ratio, density and choose between JPG and PNG format
• support InDesign object export options
• set resolution limit

Set interface language by changing lang.pre to one of the following values

• 0 English
• 1 German

For example, setting lang.pre to 1 will change the interface language to german.

lang = {
  pre: 0
}

• Embedded images are not exported. Consider to convert embedded images to linked images instead.

• for multiple instances of one image, each instance is exported with a unique filename
• the new filename is stored in the IDML as Label of the Rectangle element

<Rectangle>
  <Properties>
    <Label>
      <KeyValuePair Key="letex:fileName" Value="new-filename-a3.jpg" />
    </Label>
  </Properties>
  <!-- (...) -->
</Rectangle>
