WEBP Image Format

Thanks for all the suggestions! This is a mobile app so shelling is not an option. I will look at the command line utility and make a web service API on my server.
Update: I just converted a test webp file on Windows using this utility and it works. Now onto the on-rev server and Linux/web service.
I guess I should file an enhancement request so we can deal with webp format in LC after I get past the current disaster.
Continuing on with my headache...

Not sure if this would work but in the following article
it says there are command line utilities to convert WebP images to PNG and other formats
'Google offers up the utilities to encode, decode, and view WebP on Linux, Windows, and Mac OS X.’
C:\Path\To\dwebp.exe inputFile.webp -o outputFile
I think you could use LiveCode’s shell() function to run this to convert any of the WebP images you are supplied to get PNG versions to server to your customers.
