PNG files cannot be uploaded (upper case extension)
When I try to upload a file with a **PNG** extension, I get:

![PNG does not work](https://meta.codidact.com/uploads/U2JPpGAEW8iLEidJxrtvCBGW)

If I relabel it as **png** (lower case) then I can upload it.

So it appears to be a problem uploading images with an **upper case** file extension.

I haven't tested the other file types listed in the image.

<sub>Note: PNG is the default extension in the Windows Snipping Tool on my computer.</sub>
