In this paper, splicing on images of rectangular arrays is introduced as a simple and effective extension of the operation of splicing on strings extensively studied in the context of DNA computing. A comparison of the resulting class of splicing array languages with the local two-dimensional array languages and two-dimensional right linear languages is made. Certain closure properties are obtained. Furthermore, the notion of self cross-over of strings is extended to arrays with respect to the splicing of arrays introduced here.
