Coimage

Okay kiddo, you know what a picture is right? Imagine a picture of a cow. Now, if we take that picture and make it smaller, it might be hard to see all the details of the cow. That smaller version of the picture is called a "thumbnail."

Now, imagine we have a big picture of the cow and we want to make a smaller version of it. We don't want to lose any of the important details though. So, instead of making a thumbnail, we make a new picture that includes all the most important parts of the original cow picture. We call that new picture the "coimage."

The coimage is kind of like a summary of the original picture. It shows the most important things without being too big or too small. It helps us understand what's going on in the original picture without having to look at the whole thing.

So, that's what a coimage is, a smaller picture that gives us the most important details of the original picture. Pretty cool, right?
