Thumbnail

The thumbnail of a project on the Featured Projects row.

A project's thumbnail is the display icon which represents a project on the Scratch website and can provide an attractive appearance for a project. When exploring the website for projects, the image of the project is the thumbnail. Thumbnails also refer to icons used to represent an object of some sort in other situations.

Other Media

In the Paint Editor, costumes also have thumbnails on the left-hand side to represent them when being selected. All sounds in Scratch have the same thumbnail, that of a speaker and sound physically coming out of it. The thumbnails of all media in Scratch represent the media in a visual way. If a project is being played in the editor and the sprites' costumes are changing, then the thumbnail will always be the current costume.

Changing the Thumbnail

To change the thumbnail of your project, you must first open it up in the project editor . The exact screenshot of the stage when the project last saves will become the new thumbnail. Therefore, if the stage is blank when last saving and closing the project editor, the project thumbnail will appear blank when people browse the website and that specific project is shown.

If you do not want to take a screen shot of the project, but design a thumbnail for it, you have show the thumbnail when saving the project and then hide it when the green flag is pressed, to let any person see your project and not just the thumbnail.

To add a thumbnail quickly, you can use this script on the thumbnail sprite (be sure that is also at X: 0 and Y: 0 for best results)

when [t v] key pressed
if <(username) = [Scratcher]> then // Replace "Scratcher" with your username.
show
end

when [y v] key pressed
if <(username) = [Scratcher]> then // Replace "Scratcher" with your username again.
hide
end

Alternatively, you can use this script:

when gf clicked // This will hide your sprite.
hide 
go to x:(0) y:(0) 

show     // click this block to run it.
go to front 

Hacks

In late 2014, a hack was revealed which allowed users to set custom thumbnails, even animated thumbnails. This practice became popular, and many users tried it.[1][2] One Scratcher even wrote a program that sets animated thumbnails[citation needed]. However, many other users protested, claiming the hack was flashy and annoying to users.[3] The Scratch Team has declared that all projects with animated thumbnails would be marked NFE to avoid lag on the Front Page.[4] That means that it will not have an opportunity to be front paged, and if by chance it does, a Scratch Team member will remove it. They will rarely appear in the search results.

Bugs

Currently, there have been glitches where the project thumbnail will only change for certain parts of the website. My Stuff often does not include the updated thumbnails, where as the front page does. However, this may not be consistent among all devices and browsers. After changing a thumbnail, the project make take a while to update to where you can see the thumbnail on the creator's profile page often resulting in either a thumbnail with just Scratch Cat on it or the thumbnail before the latest change. In certain cases, the thumbnail image can lead to a broken link, though this is now rare.

In early 2017, a major bug was reported that thumbnails couldn't update, even if many days passed or the cache was cleared. This was, however, fixed later on.[5]
