Create as in how ? If you mean from photographs, then search for HDRShop which does this and is by the creater of the IBL technology. If you mean from XSI, then choose one of the float formats like MAP or CT and your redner will be in HDR format.
You can also paint them using something like Cinepaint or Photogenics...

A friend of mine did this :
took 45 !!! renders at different exposure settings
and combine them to HDR shop, 2 time-consuming, but really has unbeatable results ...the HDR was for a well-known movie...
Additionally, floating-point TIFF will serve well , after some Photoshop-HDRshop touches!

thanks for your replies~
I meant actually creating a HDRI from scratch~
since I don't have any idea of actually creating an HDRI map...
so it can be done by taking photos right? what resolutions?
then u need to take it to a HDR shop?... hmmm.. not sure what this means...
can anyone here give me a clearer explanation of what HDR shop is??
thanks a lot guys~
thanks maxFX, and tachy0n

How it works is that you take photographs at different exposure settings, and then assemble them into an HDR image in a software tool called HDRShop. Check here for more info and details:

I just have this questions about making HDR image..
which way is the best way? to me it seems like going with the chrome ball is the easiest way..
And can just a normal pictures (by normal i mean, not being panorama, probe, or cross) work too?
just a planar image w/ different exposures, would that make a useful HDR image to make a realistic lighting??

Yes, but a planar image will not be great for spherical environment map. Since the point of hdri is to use spherical maps, you should consider using a chrome ball. But it's not mandatory for hdri to work.
