Sources at the end without any references to them in the text is not a good way to cite things.
There’s no good reason to use images in your post, other than the one graph. Images of text are a necessity on Twitter, but this is a real web page, where you can just have plaintext. Images of text are completely useless for readers with any accessibility needs.
In the initial draft, I kept links next to text and the images, but I didn't like it aesthetically. So I moved all them to the bottom.
