I deal with large satellite images often in size of a few gigabytes.
When I needed to load a long image strip I could not remap images which are vert long (4096 x 81920)

Hi Mustafa,

It would be nice to investigate this issue and make the function work with very large images. Please consider investigating this and creating a fixing pull request (http://code.opencv.org/projects/opencv/wiki/How_to_contribute). Your help is highly appreciated!
