    You have it wrong. It will open up as a regular picture but if you use a program like 7zip and look inside it will have the file you placed in it earlier in there.

    Yes, in theory you could put a virus in there but it wouldn't run on open unless you somehow made it.

    I wouldn't know for sure though because I don't have that knowledge.

    I guess you could hide it in there.

    I'm usually more interested in programs that spot the program you just made and deletes it (if it was used for nefarious purposes).

    So basicly you made a program that hides any file into an archive that acts like a picture and in reality is a picture from that momment until you look at it with an achive program.
    Say i want to hide all my roms on my hdd and use your program, all would appear as pictures instead of 3ds roçms :D

    Is the picture making random or do you have to link your own pictures to each file?

    Are we talking actual stenography or just the classic "as some archives have the header at the end of the file you can decode a JPG forwards but an archive in reverse" trick?

    You don't even need a program for that...

    Just use "copy /b mypicture.jpg + pr0n.xxx hiddenpr0n.jpg" :D.

    Yes, you could hide anything inside of it. The only thing you have to worry about is file size. The more files, the bigger the file size. This is not a simple switch the filetype thing, it actually puts the files inside the picture. Yes, the code is simple but some people just want something to do it for them.

    I haven't tested how big it can go but something under 1gb would still look like a picture file size.

    As long as no one looks at the file size, you're good.

    (I don't care, hide anything you want.)

    These can be detected.
    I tried uploading it somewhere and it said "your image contains an embedded file".

    Still pretty cool nonetheless.

    I remember there was a program like that before... Chameleon or something. I encountered it on one site, where it was used to hide mp3 songs I needed (probably hoster was not allowed to upload mp3).

    Yeah, this has been a thing for a looong time. It's how some places used to mask their pirating habits, they'd add the archives to a JPG and host that various places. Though, as someone pointed out previously, some sites nowadays can just detect that and refuse to upload so it's pretty meh now. I guess this is a nice program if you don't feel like using CMD prompt or something.
