Thanks for your contribution, it's great to see you contributing again @javalord. It's really nice to see how you've improved as a contributor over the time you've been contributing to the open source community via Utopian.

I was able to replicate the issue on Android 6.0.1.

To help you improve your posts in future, I have provided feedback which I believe you may find useful.

1. I think your title could have been clearer, the following would have been more suitable SteemApp [2.0.3] - Fatal Exception when attempting to upload an image via camera or gallery.
2. Your steps were good, a few minor spelling issues but overall the steps were detailed and thought you did a good job here. Thanks for that.
3. As this is a related to the application crashing, I would have liked to have seen a log-cat. I have attached mine within this comment.
4. I would also recommend that you consider posting your issues to GitHub prior to contributing to Utopian. Did you know that we score favorably to users who contact the project owner prior to submitting bug-reports to Utopian? As per our guidelines: "If the contributor made attempts to inform the Project Owner about the bug and confirm the issue, this should be noted in the post as it will be eligible for a higher score and potential reward. Note that said attempts to contact the Project Owner must adhere to Utopian Policies for contributor conduct on GitHub and other external services."
5. Did you know that we now take into account whether or not you tried to pinpoint the issue within the code and provided a possible solution, maybe something to try in your next contribution?

Once again, thanks for your contribution and I look forward to your contribution in the future.
