I think jpegs all have the same header.  I opened one up and got:

ff d8 ff e0      

Also, I think they all have the same last 2 bytes:

ff d9

If you open your executable in a hex editor, you can search for the jpeg header and extract the image.  There might be some false positives though.

I've found the file using hex editor.
i 've  replaced the image extract from the program FILE JUICER but i got an error.
How can i replace the jpeg in the hex editor without getting an error?

HI,

You have to use a resource Editor / or Resource Hacker. It is better than a hex editor for this kind of Thing.

there is lot of of this kind of tools on the web.   google for Resource Hacker  PE     (PE is the EXE format for windows) , you should find some.

But using that is not really legal , i think. But for you personnal use it should be ok it you don't diffuse the modified version of the Exe.

I'm not sure it's possible without a lot of work.  Is the new jpeg *exactly* the same size in bytes?
