I seem to only have this problem with friends that are on TMobile for some reason. Once in a great while they can open pics that I send but easily 95% of the time they cannot. I can open every pic and video that they send to me so I am pretty sure it has something to do with Android. I had the same problem with my Eris too. I have tried resizing pics, using lower resolution, using non wide screen and nothing seems to work. I thought I had found the answer in making sure that the message had something typed in the subject line but that proved to be a bust too. I have never found an answer to this and is is frustrating.
