iView emailer black-out

[triffid]

Am running iView 3.1.3 on MacBook Pro  10.6.4.

When I send any picture via e-mail the received e-mail consists of the photo surrounded by black so any accompanying data is totally obscured. Passing the mouse over the blacked out area will indeed reveal the text but this is really rather boring for clients. Have looked at all my possibel background colour settings in both IView and my e-mail programme [ Mac  <<  Mail  >> ] amd can find nothing to account for this sudden change in behauvior.

Any suggestions please.

Many thanks
