Select from the image file name in the asset to the option field of CMS, or there is no way to display the Image?
For example, the value of the options field, enum1.jpg, emum2.jpg, enum3.jpg, enum4.jpg, keep putting the file that corresponds to it is also an asset as enum5.jpg, you want linked to the Image.
In the Image field of CMS does not go and does not repeat the upload even in the same image. Capacity is inefficient to use.
