Downloaded File is Corrupted if another file with the same differently-cased name is present

Example: I downloaded image "**U**ntitled.png" while I had another image "**u**ntitled.png" located in the same directory.

1. Downloaded the image
2. Observe the message "Saved as "Untitled.png"
3. Start a new post and go to image selection
4. Select "Untitled.png"
5. Observe the message "Failed to open file"
