Archive In-App-Purchase detect png as executables on iOS6

Question

I have created a pack In-App-Purchase on iOS6. I upload content to apple´s server. The packet has a group of png files. If I use the option: ``` Compress PNG Files = YES ``` The pngs uploaded to the server and downloaded on the App are corrupts and I cannot open it. If I open the content downloaded from the App, I cannot open with GIMP or Photoshop. So I put: ``` Compress PNG Files = NO ``` But when I try upload the content as I do the last time, I get the following error making the distributable: ``` The archive for In-App-Purchase: 'com.myapp.ProjectName.myInAppPack' is invalid. The package contains an executable at 'Content/file3.png' ``` This error appear 2 times, but I have 10 pngs. I made exactly following the same steps for all of them, but 2 are detected as executables. I sure that is a problem with headers, How can I edit them to avoid this problem?

Accepted Answer

After open the files with Exfiend and compare it, I found the problem was the headers. The pngs detected as executables had a Photoshop header. I have solved the problem creating a new png, copying the layer, exporting as png.

Then, I put only read flags on PNGs files with:

```
chmod 444 file.png
```

After clean the inapppurchase project, and archive it, it did fine.
