I would really appreciate if design of grid wasn't so scattered into two places (hardcoded and stylesheet). I'm speaking especially about fixed names for some images like down/up.gif.

Here is my case. In asp.net i have every image stored in binary resouces file, which is read by server on specific request that doesn't contain name of image but pointer into that resource file. So i cannot have simple img element with standard url path, but it must be replaced with something generated by server.

For no i made very dirty workaround, but i hope that in some future release it will be more extensible. Simple solution could be like for paging images through options for grid, which i can generate by server.
