Hello, I was working on a custom TARDIS interior, and was using chalkboards. I had tried to use the "Blob" to put an image onto the board, yet I'm not sure even how to do that. If anyone who knows how the Blobs work and respond to this, please do. It would make my day.

Blobs are essentially a Base64 encoded 2 Dimensional array of integer color values.

For example. I have a 32x18 I wish to use on my chalkboard. I can then convert the image pixel by pixel into a two dimensional array of pixel data, each element in the array representing a pixel as an integer value. We then take this two dimensional array and encode it using Base64, this then generates our blob!
