It seems like datacopy utility doesn't copy image fields well.

Here's my setup:

use testdb
go
create table Blob1(id int primary key, data image null)
create table Blob2(id int primary key, data image null)
insert Blob1 select 1, 0x1234567890abcdef
go

I tried to copy the data (single row) from Blob1 into Blob2.
datacopy utility built as part of 0.64 stable didn't work at all:

.../datacopy -SMSSQL0/anyone/allowed/testdb/Blob1 
-DMSSQL0/anyone/allowed/testdb/Blob2 -t
Error in dbnumcols
datacopy: table structures do not match. terminating


And one built out of latest CVS source worked with no errors but didn't 
copy image data:

> ./datacopy -SMSSQL0/anyone/allowed/testdb/Blob1 
-DMSSQL0/anyone/allowed/testdb/Blob2 -t
> sqsh-ms -S MSSQL0 -D testdb
[101] MSSQL0.testdb.1> select * from Blob2; -mvert
id:   1
data: NULL

[102] MSSQL0.testdb.1> select * from Blob1; -mvert
id:   1
data: 0x1234567890abcdef
