Well, if you have created it in-memory, there might not *be* any file,
except perhaps in the client's cache which you don't have access to.
You might try use Save to write to a MemoryStream, and then from a
MemoryStream you can get the raw byte[] (ToArray etc), which should be
fine for passing as a parameter to a TSQL method, for use in a
varbinary(max) [or "image" pre-SQL2005] column.

(assuming the image isn't too big; for very large byte[] you might
need to "chunk" the work)

byte[] buffer;
using(MemoryStr eam ms = new MemoryStream()) {
bit.Save(ms, System.Drawing. Imaging.ImageFo rmat.Gif);
buffer = ms.ToArray();
SqlCommand cmd = new SqlCommand();
cmd.Parameters. Add(new SqlParameter("b lob", Buffer))
cmd.ExecuteNonQ uery()

where your TSQL uses @blob
