Hmm, I just went through the steps and was able to get images  
appearing in the header. Here is what I did.

1) Dragged Data Grid onto card.

2) Dragged button onto card.

3) Named button MyCustomBehavior.

4) Set button script:

set script of button "MyCustomBehavior" to script of button "Default  
Header" of stack "revDataGridLibrary"

5) Update button script by changing :

setprop dgLabel pValue
    set the text of field 1 of me to pValue
end dgLabel

to:

setprop dgLabel pValue
    set the htmltext of field 1 of me to pValue
end dgLabel

6) Updated Data Grid property:

set the dgProp["default header behavior"] of group "DataGrid 1" to the  
long id of button "MyCustomBehavior"

7) Imported an image. ID of image was 1029.

8) Opened object inspector and opened Columns pane.

9) Created two columns.

10) Set the label of column "Col 2" to:

<img src=1029>Col2

The image appeared in the header.

Can you try those steps and see if it works for you?
