起初以为是bundle install更新的问题，但偶然发现是添加照片里其中几张xxx.png或xxx.JPG格式的图片造成的这个报错，删掉这几张图片就能成功build了。

很奇怪的是：这些被报错的图片好像并没有特别之处,目前一共遇到5张这种图片。因为这个报错，Google了很多信息，学习了不少关于bundle的知识，但仍然没有找到这张照片引起报错的原因，所以在这里向你们反馈这个错误信息。如有描述不妥请见谅：）

最后

再次感谢photo-stream团队，感谢你们提供了这样一个非常棒的照片展示工具。 PS：额外请教一下，这个photo-stream在展示图片的时候能否自动显示拍摄时间和一些可以选择的Exif信息？突然的一个idea。

Did you export your photos directly from Photos on Mac?

Did you export your photos directly from Photos on Mac? Some photos directly from Mac, and some from iPhone or Fusi-camera.Only few photos weren’t correctly recognized. I checked these photos and found no difference...Did you have a good idea?
