Handlebars - passing params coming back as null

Question

Im trying to pass a specific value into each partial.

eg :- {{> hcp/quick-hits-article image="1.png" }}

and then use this in the partial as :-

 <img
                    src="/temporary/numericPlaceholderImg{{image}}.png"
                    alt="number-one"
                    title="number-one"
                    width="26"
                    heigh="34"
                    style="
                      max-width: 26px;
                      max-height: 34px;
                      width: 26px;
                      height: 34px;
                    "
                  />

However this just outputs as

src="/temporary/numericPlaceholderImg.png"

Not too sure what im doing wrong, I need to do this 5 times just changing the number in the path

Thanks!
