 ## About the workshop
+
 Access to image-based resources is fundamental to research, scholarship and the transmission of cultural knowledge. Digital images are a container for much of the information content in the Web-based delivery of images, books, newspapers, manuscripts, maps, scrolls, single sheet collections, and archival materials. Yet much of the Internet's image-based resources are locked up in silos, with access restricted to bespoke, locally built applications. A large community of the world's leading research libraries and image repositories have embarked on an effort to collaboratively produce an interoperable technology and community framework for image delivery.
 
 This workshop will introduce the basics of the International Image Interoperability Framework (IIIF) starting with demonstrating the use cases it supports; including side by side comparison, annotations and layering of images. It will then go on to look into the Image API and provide a method for participants to upload their own images to the Internet Archive so they can access the IIIF Image support the IA provides.

+## Exercise: Cropping Images
+
+In this exercise we will use the [UCD Image Cropping tool](https://jbhoward-dublin.github.io/IIIF-imageManipulation/index.html?imageID=https://ids.lib.harvard.edu/ids/iiif/25286607) to select a region of a IIIF image (and optionally adjust other parameters), and see that the region can be be reused via its URI.
+
+### Step 1: Start the Cropping Tool with an image
+
+You can start the tool with any IIIF Image by appending the image identifier to the URL base `https://jbhoward-dublin.github.io/IIIF-imageManipulation/index.html?imageID=`
+
+Examples include:
+* A [Map of Seoul](https://collections.si.edu/search/detail/edanmdm:nmnhanthropology_8480110) in the [cropping tool](https://jbhoward-dublin.github.io/IIIF-imageManipulation/index.html?imageID=https://ids.si.edu/ids/iiif/NMNH-81-10767) (from Smithsonian)
+* An [Emroidered Screen with 10 panels](https://collections.si.edu/search/detail/edanmdm:nmnhanthropology_8337004?q=korea+art&iiif.enabled=true&record=8&hlterm=korea%2Bart&inline=true) in the [cropping tool](https://jbhoward-dublin.github.io/IIIF-imageManipulation/index.html?imageID=https://ids.si.edu/ids/iiif/NMNH-NHB2017-00559-000003)
+
+### Step 2: Explore selection of a region
+
+Use the graphic region selection tool and experiment with the other parameters.
+
+### Step 3: Use the cropped image
+
+Look at item 4 within the cropping tool:
+1. Preview the cropped image
+2. Download the cropped image
+3. Copy the cropped image URI into another browser tab to see how it could be reused by reference on any web page
