How to read AX 4.0 db image from SSRS 2005/2008

Dear all,

I am trying to display images from a SSRS report by reading a Ax 4.0 database without any luck.

search from the forum give me 2 options by using

1. remove first 7 characters from fields Binary. ( substring (image, 7, datalength(image)).

2. follow MSDN http://msdn.microsoft.com/en-us/library/ms156342.aspx by using

=System.Convert.FromBase64String(Mid(System.Convert.ToBase64String(Fields!ImageFieldName.Value),105)) 

** I also try other length because we are using Chinese_taiwan collation.

both seems not working. Does anyone has any sucessful experiences? Thanks in advance.
