Hi,
Options include.... adding the pictures into a table within your DB, which is not a good idea as it will bloat beyond belief.
The fol link discusses a third party app which may assist.
http://www.experts-exchange.com/Microsoft/Development/MS_Access/Q_23923285.html?sfQueryTermInfo=1+continu+form+picturWhen u attempt to link a pic to a continuous form it wiil show the same pic for each row. When u click a new row it will update all rows to the new pics. IMHO the third party app discussed above is prob the only solution although I have never used it.
I know not the news u prob want, but hope it helps.
