I wrote a program which creates TIFF images. So I ve created a 30000x15000 TIFF image and everything went well and I can see it in Photoshop CS.

I retried with a 60000x30000 TIFF image and the creation was correct and I have a 5,3 Go file (created with PACKBIT compression). BUT I can not open it in any software (even Photoshop CS doesn t work).

TIFF files are limited to a maximum 4GB file size. Most TIFF software will be limited to 2GB file size due to interpretation of the TIFF spec, and operating system limits.

Is there a limit of the size of a TIFF image? (maybe it s juste a memory problem, I have 2 Go ram on PC/Win2000 ?)

Probably you need dedicated TIFF viewing software. Writing the TIFF as tiled TIFF will help readers considerably.
