@luckynos7: Jpeg is a lossy format not lossless, the only real alternative to jpeg would be PNG its a lossless format and has the added bonus of being able to retain transparency. I use it pretty much all the time. PNG files are considerably bigger than jpeg for obvious reasons but at least you retain all the image, so its a pay-off small size and degraded image, larger file size and good quality image.

2) is it possible to have a series of batched jpeg files which fall just under the 100MB limit set by those who’ve been flicker’ed? ‘:-)?

I don’t get what you mean by this please explain more…!

PS: 3) is there a better alternative/compression to JPEG which flicker might accept?

as you may/or may not know JPEG is a lossless format thus the important question here is there; 1)likely to be degradation when it comes to uncompressing and retrieving files/folders, hidden/backed-up files/data in this way and 2)is it possible to have a series of batched jpeg files which fall just under the 100MB limit set by those who’ve been flicker’ed? ‘:-)?

Hi,

Is their a way to reversed the process? i try to hide my files but before archiving it, I put a password on the archive and hide it on image..now the problem is when i open it on Winrar I can open the archive but i can’t extract it and giving this error..

“! D:\test.rar: CRC failed in the encrypted file D:\test.rar (wrong password ?)
! D:\test.rar: No files to extract”

I swear the password is correct since i was able to view the archive..i just can’t extract it…:(

any help will be appreciated..

TIA

Hey, thanks! Just what I was looking for! I tried it and at first it said “The system cannot find the file specified.”

So, I had thought maybe this guide was outdated, seeing the top comments were in 2008 and I’m using Windows 7, which didn’t exist when this instructional was created. I looked over and yes, I had typed it correctly.

However, it turns out that I thought to shorten the filename and remove the numbers and underlines in between words. I made the jpg file to be four letters long.

It worked! The command prompt listed the image name on the next line (after pressing Enter), then, on the next line the .rar file (which is 1GB large!), and, then, after a moment, it said “1 file(s) copied.”

Thanks for the guide!!! =)

I tried this:

C:\>copy /b some.jpg + movie.avi other.jpg

It works.

Problem: not able to see movie even after changing the extension of image file to .avi.

It says: “To get your rar file, just change the extension .jpg of picture.jpg to .rar , and open it. To hide, change the extension back to .jpg.”

I’m wondering: Once you created your hidden picture file, how do you edit and add new info, i.e., MS Word docs, notes, mp3s, etc., and put the new info back in the hidden picture without going through all those steps again?

Thanks.

I’m having a similar problem to someone in a previous post. Either the picture works when I do the following:

copy /b testpic.JPG + hidden.rar testpic.JPG

or the archive works when I do the following:

copy /b testpic.JPG + hidden.rar hidden.rar

I’m using Windows 7. Would that be the cause of the problem? I’ve also tried a few other combinations that give me errors when I try to extract the files. I also tried like an above example suggested, using different sized images. I’ve tried big and small, and I get the same results.

Any advice or ideas on how I could get this trick to work would be greatly appreciated.

Thanks.

Instead of using paid software like WinRar, one can use freeware like IZArc2Go. I know that many people prefer use pirated copies of WinRar, so its better not to use WinRar. But if You are using, WinRar or other softwares like Peazip or 7-zip no need to worry, download portable version of IZArc2Go. It works , I tried it with zip files. Remember “7z” achives better compression than “rar”!

on the CMD part, when I placed the *.rar first, the jpg didn’t work and the hidden files did.. when I placed the *.jpg first the picture worked but the hidden files didn’t.

Shukoor… did you even read the article? /facepalm

OK SO, obviously this can be used to hide any file inside of any other file, but the fact that the jpg still works as a picture is the great part.

That said, I experimented around after seeing someone ask about using an avi file since they are large to begin with. After about five minutes I discovered the following:

Running the following command hides the file as expected however the avi video will not play and the rar archive is not accessible.
Doesn’t work: copy /b movie.avi + filetohide.rar movie.avi
——

However (and this is the great part) this command:
copy /b filetohide.rar + movie.avi movie.avi
Does work! This file successfully extracts from winrar and also plays the video and audio flawlessly.
