Another Technical Question
 

Can someone tell me how to convert a WEBp file to a JPEG, so I can post it to the forum?

There are numerous sites that do it. First one in the Google search results:

https://cloudconvert.com/webp-to-jpg

Fango

There are free converters online, just google it.
Found this one https://image.online-convert.com/convert/webp-to-jpg

You can also just rename the .webp file extension part of the name to .jpeg or .jpg
This will show it in Windows Explorer previews but won't always work for editing/cropping etc.. where you would have to convert it.
Webp is based on jpg/jpeg
