How to show symbols above and below the summation (\sum) symbol using markdown for Github-Pages?

How do I show symbols above and below the summation sign using <img src="https://render.githubusercontent.com/render/math?{}> ? Is it possible? If not, what are my other options to render such a math symbol?

I closest I got is <img src="https://render.githubusercontent.com/render/math?math={\color{black} \sum_{d=0}^{d_{max}}}"> which give ${\color{black} \sum_{d=0}^{d_{max}}}$ . But this layout is not what I desire to achieve.

Solution

I discovered that https://render.githubusercontent.com/render/math? is using latex commands. Hence, the command \displaystyle needs to precede \sum to achieve the format that I desire.

Therefore <img src="https://render.githubusercontent.com/render/math?math={\color{black} \displaystyle\sum_{d=0}^{d_{max}}}"> gives ${\color{black} \displaystyle\sum_{d=0}^{d_{max}}}$ .
