How to make tiles of very big file?
I have a very big map,but i found that i couldnt save it as *.jpeg file(if the file of map is over 30000*30000, photoshop can only save it as *.raw,*.tif,*.psb ),so i couldnt convert it to tiles by Zoomify.
But i think there must be some way to do it,just as the google maps and so on.
How i can do it,please help me,thanks a lot!

Inappropriate?How are your programming skills?
I've done this a number of times, typically using the Python programming language to slice up large images. I can post code snippets here if they'll be useful to you. -
Inappropriate?with great appreciation for your help, please post it to me, i hope that will be work, thanks again! -
Inappropriate?I was able to use Zoomify with .tif files. You should be able to as well... -
Inappropriate?yes,you are right! thanks for your help!

Inappropriate?I see this post is quite old, but the way that I deal with large images is as follows...
1. If you have Photoshop CS3 or later, you can export the the tiles in Zoomify format.
2. If you have GlobalMapper 10 (brilliant piece of software) you can export VE, WorldWind or Google Maps tiles.
I have found that using GlobalMapper is a far better option as you essentially have limitless image size if you deal with your map in bite size chunks and also convert to ecw format which makes a huge difference.
The other major advantage is that GE, VE and WorldWind tile numbers are unique, so you can deal with your map in smaller pieces whereas with Photoshop, you have to have the whole image loaded before you can export in Zoomify format.
Once you have your tiles in VE (my prefferred choice) format, you can adapt one of the ModestMaps mapprovider.as scripts to load your custom tiles.
