<font face="Comic Sans MS" size="3">I (we) can second the stuff about the performance issues with large MRSID files. We tried them once, and decided to use straight JPEG tiles instead. The JP2k files were a big issue too, and since the read only aspect of the tiles didn't really require JP2000 files, we didn't put any more effort into it.</font> </p>
