Can I assume that you are using Amarok v0.8.1b3 and enabled the Obfuscate File Header [Experimental] function?
Possibly the same bug: #16
I failed to reproduce this bug. It seems to happen occasionally 🤔
If you can find a way to reproduce this bug consistently, it would greatly aid in resolving the issue.

Recover the Corrupted files

1. Download and install this Special version of Amarok (v0.8.1b3-sp-e57eb09).
2. In More Settings -> Switch FileHider Workmode of that special Amarok, make sure the Obfuscate File Header [Experimental] switch is toggled to OFF.
3. Put the corrupted files into a directory, and add the directory to the hide list in Set Hide Files.
4. Press the Hide button in the main activity.
5. In More Settings -> Switch FileHider Workmode, toggle Obfuscate File Header [Experimental] to ON.
   (In the normal version this switch is unavailable and a note says Options are unavailable until Unhide.)
6. Press the Unhide button in the main activity.

Hopefully, your corrupted files (images) will be recovered.

Thank you some pictures are back but not all, and it's my fault from first i killed the app from background while the app hiding files because i select pictures file by mistake thanks.

Sorry to hear that. Perhaps you can try the recovery process again.
If still without luck and the images are really important to you, you can try recovering the images manually:

• Amarok only read the first 8 bytes of each file, calculates their ones' complement and writes the result back.
• As Amarok reads and writes files sequentially, theoretically will be only one file is "real" damaged, while others are just not reverted.
• Fixing them manually: Open the image with a hex editor, replace the first 8 bytes with their ones' complement — e.x. 1 to F, 2 to E and so on.

To avoid it happening again, I've refactored the FileHider and added some insurance work during the process. 8261481

Well, I wrote a simple script to do this. Python3 is required.
