No Photos in [Yahoo] email - Red X's

[FONT= "Comic Sans MS"]Is there anyone that can tell me why I can recieve pictures in yahoo e-mail, but when I forward them to my friends, they recieve a bare box with a red X in it. Also it seems after checking my email this morning that incoming photos are now missing. I have the dreaded red X now in the in-coming and outgoing email.

Someone told me to go into IE tools and go to the advanced tab, Go then to Multimedia and make sure my Show Photos box was checked. I did this and I stilll get the red X. Can anyone tell me what I am doing wrong?[/FONT]
