Since we have just deleted our\u00a0IMAGE_RESOURCE\u00a0<\/em>from our\u00a0DISPLAY_SCREEN<\/em>, the trials will now not contain any pictures. We therefore need to add the\u00a0IMAGE_RESOURCE\u00a0<\/em>back in.\u00a0But this time we don’t just want one particular picture to be shown; we want all of them shown, one at a time, to give a series of different trials.<\/p>\n

Before we get to that, note how under the Properties\u00a0<\/i>panel of the\u00a0SEQUENCE<\/em>, it now has an\u00a0Iteration Count\u00a0<\/em>of 4, as below:<\/p>\n

\"ic\"<\/a><\/p>\n

This is because there are 4 lines (trials) in our datasource. This means that we will now see what is in the\u00a0SEQUENCE <\/em>four times, as it will run through everything in the SEQUENCE <\/em>four times. The below sequence of events will be repeated once for each row in our datasource:
\n<\/em><\/p>\n

\"seqorder\"<\/a><\/p>\n

 <\/p>\n

 <\/p>\n

We want a different picture to be displayed for each of the four times\u00a0DISPLAY_SCREEN\u00a0<\/em>will be run. To set this up, go to the\u00a0DISPLAY_SCREEN\u00a0<\/em>action in your\u00a0SEQUENCE\u00a0<\/em>and insert a new IMAGE_RESOURCE<\/i>, as you did before. Select any of the four images and insert one of them, as below.<\/p>\n

\"\"<\/p>\n

Next, select the\u00a0IMAGE_RESOURCE\u00a0<\/em>you have just added. On the left side of the screen, you’ll see that, like everything else, the\u00a0IMAGE_RESOURCE\u00a0<\/em>also has special properties associated with it in the\u00a0Properties\u00a0<\/em>pane. In order to present a different image each trial, we just need to point the\u00a0Source File Name\u00a0<\/em>to our datasource, rather than the name that it has to begin with. When you click on the\u00a0Value\u00a0<\/em>for\u00a0Source File Name<\/em>, you’ll see a button with three dots appear. Click that button. It will open up a new window that will enable you to point the image name to anything you want. In this case, you want to point it to the image_name column in your datasource, as below. To do this, click on the datasource node and then double-click on the image_name column to set it as the new attribute.<\/p>\n
