I am testing a PhotoChooserTask based Windows Phone 8 application in an emulator. I want to test a specific image. Is it possible to somewhere add your own images to the sample photos that the emulator provides?
To be more specific, I want to test a library for decoding JPEG 2000 images, but it is not clear to me how to access arbitrary images on Windows Phone? FileOpenPicker compiles, but it throws a NotSupportedException when the constructor is invoked. The PhotoChooserTask is currently my best bet, but so far I have not been able to figure out to access images that are not part of the sample photos. And as far as I have been able to find out, MSDN documentation also does not provide a good enough answer.
Upload the photo somewhere online, go to that URL in WP8 IE10, tap and hold and click “Save Picture”. The picture should now be in your “Saved Pictures” folder which is visible in the PhotoChooserTask.
FileOpenPicker isn’t currently supported on WP8. It’s only useful for choosing photos from C++ code since PhotoChooserTask is a managed API and is unavailable to C++ apps. Read more about that here @ http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj215901(v=vs.105).aspx
