Use a linked picture to dynamically display pictures in your presentation. The picture that will be shown is deducted from the information of your data connection.

Click Insert > Picture > From file in your PowerPoint menu. Now click Browse in order to select your default picture. If you don't have a default picture that you can use, just insert an empty picture with the correct dimensions with the same color as your background.

Also note that it is best to always use images of the same dimension as all images are stretched to fit the first and initial image place holder.

At the Insert button you will get more options to choose from after clicking the small arrow in that button. Choose Link to file.

Click DataPoint > Linked object properties to continue.

Select an existing data connection from the list. These items are the data connections you have defined as data sources for this presentation.

Choose a column from the available columns list. These are all the columns that DataPoint could find in the defined data connection. The content of the column refers to the picture you want to display.

Enter the row number of the record you want to use. Normally this starts with value 1 but in case you want to display multiple data rows on 1 slide, then you can put multiple pictures on this slide and increment the row number for each new row.

Here you can specify what information can be found in the chosen Column field. This field will always refer to an image. This reference or path could be the full path to the picture but it could also contain only the filename. In that case you can set here what the default folder is to look for the image.

Set Folder, filename and extension when your field contains the full path to the image. Folder and filename can be chosen when the full path is not including the extension of the file (e.g. jpg). When choosing Filename and extension you will be able to set the folder to locate the image. And finally the Filename only can be used to set the folder and the extension to a constant.

Click Clear to remove all DataPoint properties from the picture and return to a normal and static shape.
