Help, please.
Recently, Outlook Express has removed access to some photo enclosures from relatives in the last two weeks.

The method of preparing the picture seems to be part of the problem; the same picture sent jpeg arrived, but another (gif?- forgot to ask, but it had been put through Adobe) was blocked.
The message was "OE removed access to the following unsafe attachments in your mail: Porteous Road View." It was a view of fields and mountains from the front porch.

The same happened to one sent by a son-in-law of his boy in Little League baseball uniform, but he is away and I can't determine his method of transmission. He sent it twice; the first was refused as too large by a back-country dial-up for one recipient was the one stopped by OE to me. The second, smaller, came through to me without warning. I have cable broadband, etc., supposedly all the bells and whistles.

I have not authorized nor can I find any blocking instructions with the OE that I have. I looked at the Programs instructions; to me they were gobbledegook. It is Outlook 6. Is there something in their system that does this? Why are some methods of photo transmission censored and not others?
Any suggestions?
