1. A method of providing a montage, said method comprising: projecting a plurality of globally matched images collectively corresponding to at least a portion of the fundus according to a geometrical projection model, the geometrical projection model corresponding to geometrical and optical characteristics of an eye and of a camera position relative to the eye to receive an initial geometrical representation, wherein the initial geometrical representation is provided by a mapping value for each one of the plurality of images and a distortion value related to the eye and the fundus camera optics; and adjusting the initial geometrical representation, including repositioning an image from amongst the plurality of images using an updated mapping value for the image, in accordance with a predefined strategy.
