Add extension when download image

[Edo2610]

Describe the bug

Hi,
I load an image on photosphere using the base64 source and when I donwnload the image it will downloaded without extension and with the first characters of the base64 code as name

There's a way to customize the download name of the image adding also the extension?

Thank you

Additional context

If I change the extension of the downloaded file, the image is shown correctly, so the file is good!

Two improvements for the next version :

• will use panorama.[type] as default name when the panorama is base64
• add downloadName option if needed
