I am not too much clear your question but let me guess. I think you want to send the total folder as a attachement if so then we can do one thing.
you just zip that folder by FM script and finally attach that zip folder.
Does it make sense ?
No I need to only one image file which store in Container
You can do one thing. Before "Send Mail" script step do below steps
1> Set variable $FilePath = Temporary path & FileName
2> Export Field Contents of container field having image to $FilePath
3> In the "Send Mail" step attach file with $FilePath.
Now this process will attach your image in the send mail inside the container field.
I think these above steps will solve the problem.
Thanks it was working fine now
Set Error Capture [on]
If [not IsEmpty (Place::Images | Container )]
Set Variable [$PATH; Value: Get (Temporary Path) &”Staticmap.png”]
Export Field Contents [Place::Images | Container; “$PATH”]
send mail [************]
