How to enter an adapted image into endnote

How to enter an adapted image into endnote.

I found one reference here that said to use prefix option for the in text citation, but that does not change the bibliography entry.

De oude polder ten zuiden van Wilnis. (unknown).   Retrieved 8 maart, 2013

Fitch, J. (2011). Smile Reef Playroom.   Retrieved 13 maart, 2013, from http://dribbble.com/shots/327787-Smile-Reef-Playroom

it should be

De oude polder ten zuiden van Wilnis. (unknown).   Retrieved 8 maart, 2013

Fitch, J. (2011). Smile Reef Playroom.    Adapted  13 maart, 2013,  from  http://dribbble.com/shots/327787-Smile-Reef-Playroom

Sorry for the dutch in there. Does anyone know how to do this? It is APA6th by the way

Which specific reference type did you use for the record for this this citation and do you use that reference type for any other citations that would require the “retrieved” rather than “adapted” wording in the bibliography?  

If not, then you just need to edit the output style replacing the word retrieved with adapted for that reference type template in the bibliography section of the output style.  - edit the output style via Edit>output style> edit “APA 6th”, go to the Bibliography>tempaltes section and find the reference type, and edit the wording, leaving all the other surrounding characters in place.  Then SAVE AS to a new name, and in the word document change the output style to the new name.  

I used that specific type (website) for multiple pictures, some adapted others not. I could duplicate that type and change te wording! Thanks
