It's not just viruses; it's malware too. And your computer could already be infected, meaning you have no idea that the image you send contains the virus or malware.
Normal looking images can hack your computers. You should not presume the image files as "innocent" anymore, as they can hide malicious code deep inside its pixels that could infect your computers. Photos can be embedded in emails as they are in webpages—and do their dirty work when you open the mail. Steganography, which in a digital context means the art of hiding data in another type of file. Malicious code can be hidden within the pixels in any digital image. Users typically don't think of common image files (such as .jpg, .png, .bmp, and .gif pictures) as risky or insecure, but it's possible to conceal malicious code in an image. A graphic can easily contain additional bits interwoven within the image, without noticeably effecting the image's appearance. That additional data can include code, which is encrypted to make it harder to identify. Luckily, such an altered image can't do much by itself. No image viewer will see or know what to do with that code, even if it isn't encrypted. But malware developers often break up their code into multiple pieces and distribute them separately to avoid detection. The information hidden in a picture could contain instructions useful to another piece of malware on your computer. Once your computer is infected, what you send can be also. In other words, a device can be compromised, in theory, after simply opening a picture.

Since the membership of the list is not what it once was, maybe the ones who make the rules would be open to putting it to a vote of the remaining members?? Is it possible to get a virus from an embedded image? I don't know the answer to that, but I know a lot of forums allow that, so I doubt it's a problem. Who would like to have a vote? If that's acceptable, count me in for allowing it. If not, I'll abide by the rules.
