Thank you

Original KIO4_Base64 Extension is updated, you can get it here:
http://kio4.com/appinventor/277i_extension_imagen_string.htm
should be the same link as on your site
Why? What have I forgotten and not added in the program code? Please Help.

If you want to save to your ASD, do it like this:
the block expects a filename in address, I do not believe this will handle google drive links.
@Juan_Antonio may know different!
Thanks, but not support google drive. do you have solution for google drive files. 
I think that.
Use the web component (once it is fixed!), that way you can give it a filename when you download.
Not working!
I know exist solution with google app script but looking for easy way.
So why was a 120kb png file on google drive redused to 2kb file in smartphone that can't be shown? Instead of displaying a filename, how do we display the picture? because the file is just 2 kb.
That is not my experience.
Show your blocks and a text of your link so that I can test for you
Set an Image component
Image1.Picture = fileName
Yes that working. Sorry.
