Good idea! I have to keep bending my eyes to read the small numbers.... ;-)
An intermediate solution might be if you insert the graphics with a link to the graphic, then you can display the graphic itself larger...
like this:

Good idea, though I've always done it like this:
i.e.
I hadn't done that because I normally just right-click and then open the image in a new tab, but from your example, I see that the readability is much better this way, so I just updated all three images in this week's post.
That is also a possibility. I haven't been able to do that with Markdown yet. Thanks for the tip!
Sometimes I also open the image with a right-click. But often the image is still quite small and I have to resize it manually in the address. That's why I prefer one click. :-))
Agreed, and it gets blurred when you expand the size. The images definitely look much sharper this way. I hadn't been aware of that difference before.
