Why are jpg pictures in body of email page (yahoo hotmail gmail) not displayed a few times without reason?

On fairly rare occasions received emails with jpg pictures which should be displayed in body of the email appear as small squares with a red x in them and with their file names and no reason is given. The pictures of such emails cannot be seen in Yahoo Mail or Hotmail or Gmail or even sometimes in Windows Mail (of Vista). Sometimes they can be viewed if you open the attachments one at a time when they should all appear in the body of the email page. My computer has Vista Home Premium. I had identical email problem with my old computer with XP and IE6. For some strange reason most of the blocked jpg pictures are innocent religious pictures. Most adult porn pictures can be seen without any difficulty. No reason for blocking and a way for unblocking is given.

.jpg is just a format to hold the file like.doc .wav or .mp3


in emails malicious software can be embedded in the .jpg or any file, in this case you have to open the picture yourself. It's keeping your computer safe it's closed to protect from viruses trojans ect. if you open this file it means you trust it and your computer is now prone to whatever was inside it.
