Why are there two URL options in the Images admin form?
There are two images that can be created for each ReportIt icon type. The first URL provides the reference to a smaller version of the image, while the second URL provides the reference to a larger version of the image. The larger icons will by default be used when displaying ReportIt on a mobile device. However, when defining your Incident webpages you have the option to specify to use the smaller icons should you wish to.
