[jQuery] change filename variable at jquploader

[jQuery] change filename variable at jquploader


For upload image,I always rename the file to md5(microtime), so there
will not be duplicate file from the user. I try using jquploader for
the upload field. The problem is, I cant change the filename that
generated from jquery (hidden field) become md5(microtime).
Anybody knows what I could to to rename this filename on the hidden
field ?
