Image not displaying correctly
Something really weird is happening on my website, there is an image that is not displaying!

The problem seems to be file extension. Theoretically, the file extension is *.png* (but it seems it is *.PNG* somehow)

**Here is a screenshot**

**How this happened??** and **How can I change the image extension back to *.png*??**

I really don't want to put *.PNG* on the CSS file!
