Using Front Matter Variables and Partial Image Filename

[softlimit-ben]

Wondering if it's possible or what you'd recommend for including Front Matter variables in your image_tags? For instance... how would I go about getting something like the following to work with Jekyll-SrcSet?

{% image_tag src="img/work/{{ post.project-id }}_featured.png" width="250" %}

I know there's the option to leave off the quotes for variables.. but that doesn't seem to work in the case of both a Variable + String. Any ideas?

Thanks.

Ok... seem to have answered my own question. I got this to work using capture. So, the final output looks something like:

{% capture project_image %}img/work/{{ post.project-id }}_featured.png{% endcapture %} {% image_tag src=project_image width="250" %}

Actually... nope. That just captures the first instance. Hmm...
