As malware reverse engineer then i can say that malware almost never copies itself to image formats, only exe files and rar
sometimes it automaticly seeds a torrent file also

Photos can never infect you because they cannot contain code.

Effectively you could embed anything you like in a picture. For example in the EXIF data. If a photo viewer in fact has a vulnerability you could (under certain circumstances) cause a buffer overflow and execute arbitrary code on the targeted machine. It wouldn't be the first time that something like that is being used to take over a machine.
That has happened a few times through the history of computers!

Facebook has virus detection and it will scan your uploads and if they find out that the file you're trying to upload has a virus, they will stop you from uploading and ask you to scan your computer for virus and then re-upload.

I think the normal images are fine, such as jpg, jpeg, bmp, tif, gif formats.

Nope, there have been many examples of that happening.

A good fake, make an executable that starts an image program and loads a picture. Meanwhile, it's an executable that can run virus.
The user would need to be fooled into thinking '.jpg.exe' is an image. This kind of virus cannot be shared trough facebook, as far as I'm aware.

A virus is executable code and it would thus require that the image is executable. It could be hidden as a .jpg.exe
It is unlikely but not impossible in theory. In practice, the transmitter facebook hosting does not permit .exe uploads.

If the transmitter is another hosting provider then it is plausible.  A user would be required to download the executable and run it.

Probably you won't infect facebook website, if this would be possible an hacker would have done it before.

From what I understand the only way you can get a virus from an uploaded image is if the image file is infected, if the image file is clean which you can check using numerous ways then there is no way a virus can be passed.

Can somebody show a virus infected image file?

No idea where you can get one, but according to http://stackoverflow.com/questions/9675941/how-can-a-virus-exist-in-an-image, it may be possible hide malicious code within an image file.

First of all it depends whether the photo file is compromised to begin with. I mean it's rather difficult to embed a virus or malware into something that get interpreted. Also, Facebook re-encodes your photo, as far as I know. They'd be pretty stupid not to pay attention if their customers are uploading infested pictures!

thanks, im going to put them on a usb & upload via a work computer which should eliminate any virus, im not yet up to speed on linux

i hoped facebook couldnt hold a virus on uploaded pics Undecided

Er... Dude, get up to date on Linux. Windows is how you got virus in first place. Lol.

Download mint Linux if your computer is less than 3 years old. Download puppy Linux if it is older. Install. Installation with formatting will delete everything off drive including viruses. Very easy to use. You will be up to speed in less than 2 hours. No more viruses. For all practical purposes, there are no Linux viruses. Unless you are target of us govt or you announced online your IP address and the fact that you have 2000 btc in a hot wallet on your computer, then you don't have to worry about viruses with Linux. Too few people use Linux so it is more productive to write windows viruses.

I would not have suggested otherwise, i think Linux will resolve it.

In a world of peaches, don't ask for apple sauce
Can you get image files infected? I don't think unless the OS is rigged to interpret the pics as code. So uploading only your pictures to some hosting and then downloading them to an uninfected OS shouldn't get it infected I think.
