The alternative text can be reused in multiple documents. Whenever the file is copied or moved, the metadata stays with it. The pros are that the alternative text becomes part of your image file. Let’s summarise the pros and cons of having the alternative text as part of the metadata. From now on the alternative text will stay with the image file whenever we move or copy it. To apply and save our modifications we click the little tick in the lower right-hand corner of the Metadata pane. We type “Alice, the rabbit and the mad hatter at the tea party”. For our purpose, it is sufficient to add a description to the image. InDesign will be able to access any of these attribute values and add their content as alternative text. We will take a closer look at the IPTC Core attributes in order to edit the headline, description or title. Each of these sets is defined by different standards or media types. Metadata attributes are grouped into different sets, such as File Properties, International Press Telecommunications Council (or IPTC) Core, IPTC Extension and Camera EXIF data. Bridge indicates editable metadata attribute fields with a little pen to the right of the field. Other metadata add additional information to the file without modifying the image itself. Some metadata attribute values cannot be changed without modifying the image such as file format, creation date or resolution. On the right-hand side, we see the metadata of the file. The program will now open a preview of the image. We can use the file browser to select the file that we want to add alternative text to. After starting Bridge, the program opens a file browser for us. For our example, we will use Adobe Bridge as it is included in Adobe’s Creative Cloud suite. There are many programs on the market that can modify the metadata of image files. So let’s see how we can add alternative text to an image file. When we copy an image, its alternative description will be copied as part of the image file as well. ![]() This means that we can reuse this description in many other documents without having to retype the alternative text. Alternative text can be stored in the form of metadata inside the image file, as part of the image. Images in accessible e-books require alternative texts. Before we start using InDesign itself, we need to think for a moment about the images that we want to include in our InDesign documents. Let’s see how we can create accessible e-books with Adobe InDesign. If you are only interested in creating accessible e-books with Adobe InDesign, then this lesson is for you and there is no need to watch the chapter about PDFs. ![]() If you have watched that chapter, you will notice some repetition here. This chapter is similar to the one about creating accessible PDFs with Adobe InDesign. We will not explain how to lay out, design or print documents. This course focuses on how to improve the accessibility of your e-books. We assume that you already have basic knowledge of how to use InDesign. Please note that this is not an InDesign course. InDesign has native support for creating e-books based on the EPUB format. InDesign is a commercial product, available on a subscription as a single program or as part of Adobe’s Creative Cloud suite. Its primary target groups are graphic designers and desktop publishers.
