Simon MacDonald commented on CB-17:
-----------------------------------

My fix resolves the problem where the webview is caching the resize.jpg image. If you want to get the original file do a getPicture but don't specify a new targetWidth or targetHeight.

> If you request a picture from the photo library and you provide a targetHeight/targetWidth we create a temp file in the application cache directory called resize.jpg. If you then show this file in your PG application it works fine. Any subsequent calls to getPhoto using targetHeight/targetWidth will create a new resize.jpg but when you go to display it in your app it shows the first one as it is cached.
> Workaround: If your picture is small enough use DATA_URL
> Here is some code to reproduce:
> function getPhoto(source) {
>    sourceType=source;
>        window.resolveLocalFileSystemURI("file:///mnt/sdcard/Android/data/
> com.phonegap.helloworld/cache/resize.jpg", fileExist, onFail);
> }
>   //,allowEdit: true,targetWidth:390,targetHeight:390
> function fileExist(fileEntry) {
>                alert(fileEntry.fullPath);
>        fileEntry.remove(removeSuccess,removeFail);
> }
> function onFail(error) {
>         navigator.camera.getPicture(onPhotoURISuccess, onFail, { quality:
> 75,
>              destinationType: destinationType.FILE_URI,
>              sourceType: sourceType,targetWidth:390,targetHeight:390});
> }
> function removeSuccess() {
>        alert("file Success Removed");
>         navigator.camera.getPicture(onPhotoURISuccess, onFail, { quality:
> 75,
>              destinationType: destinationType.FILE_URI,
>              sourceType: sourceType,targetWidth:390,targetHeight:390});
> }
> function removeFail(error) {
>        status("Image file delete failed (error " + error.code + ")");
> }
