I made a project with an animated thumbnail GIF in a PJS program and a guardian told me not to do it.
Please don't show users how to make animated program thumbnails in PJS, and don't do it yourself, so it doesn't become a widespread practice.
I know that KY made an animated thumbnail program in HTML and it got to the hotlist.
I want to ask the Khan Academy guardians if it is okay to do animated thumbnail programs in HTML.
Thanks for reading.
