There are chunkedImage sources. I would highly suggest using such a thing. Then you can put your image in, load it as chunked image and it should work as intend.
(I wrote one for Kamaya, its actually not that hard to do. Just some serious TPixmap.Paste fun on loading of the chunked image and a temporal RAM overhead)
