Please try this one
 
EncodedImage myimage = EncodedImage.create(Storage.getInstance().createInputStream(storeName));

I'm assuming that's an "image" downloaded with ImageDownloadService.

Once of the main reasons we deprecated that class is the fact that it downloads to a storage format that isn't a valid image file.

If you are migrating away from ImageDownloadService name your image files differently to avoid collision with old files.

Thanks Sadart and Shai for the info
