How to display package images
To allow package images to be displayed on the webstore you will need to open the Category edit page and find the drop-down option marked "Packages Display type". This option will need to be set to "Display the packages in a grid with their images included".
Once this is selected you will be able to go to each of your Package edit pages and upload an image through the interface on the right-hand side. The recommended size is 190x165px.
If your image has slightly different dimensions don't worry, as it will be automatically resized after it has been uploaded to fit the recommended size.
