# Image Data Pack

  

This is an open-source application based on  Adobe AIR runtime. It allows to save your custom data into PNG image file and restore it back from image.  

  

[Download Image Data Pack installation file](https://github.com/burdiuz/png-pack/raw/master/ImagePack.air)  

> **Note:** This is cross-platform application that can be installed on Windows, Mac or Linux machine, but you will need to have [Adobe AIR runtime](https://airsdk.harman.com/runtime) installed before installing Image Data Pack application. Since [Adobe stopped support of Adobe AIR](https://blog.adobe.com/en/publish/2019/05/30/the-future-of-adobe-air), it passed full control of Aobe Flash/Air to [HARMAN a SAMSUNG company](https://www.harman.com/) and runtime can be downloaded from their website, [download Adobe AIR runtime](https://airsdk.harman.com/runtime). It is still fully functional application and can be used like 10 years before.

> **Note:** This application uses XOR encryption if password was entered. This is weak type of encryption and if you want to really encrypt data, please, use other application for this.

  

### How to use  

#### To add data to the image

 1. Select image file by clicking "Browse" button, this image is named "Storage Image" in this application because it will store all the data you want to hide. After loading image you should see it on the top left corner of application window.

 2. Dependent on what you want to save -- file or plain text select tab "Add file to Storage Image"  or "Add Text to Storage Image".  

 3. Under this tab select file with "Browse" button or enter text into text field. For file you can add comment and select checkbox to "Save original file attributes".

 4.  If you want to encrypt data, specify password in *Enter password here...* field. Encrypted data will be displayed with "key" image over file icon.  

 5. Click on "Add to Storage Image" button to add selected file or entered text to the image.  

 6. To add new file or text repeat from step 2.  *Note: You can add data to image that already stores data.*  

 7. Click on "Save Storage Image" button to save selected data to current image file or "Save As new Storage Image" to save Storage Image and data into another file, in this case original file will remain unchanged.

    *Note: Nothing will be changed in the Storage Image before you click "Save Storage Image" or "Save As new Storage Image". "Save Storage Image" will update original image file!*
