Subject: tpl: Update Twitter card to also consider images in .Resources
X-Git-Tag: v0.35~16
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=25d691daff57d7c6d7d0f63af3991d22e3f788fe;p=brevno-suite%2Fhugo

tpl: Update Twitter card to also consider images in .Resources

The new lookup order:

1) Page.Params.images if set
2) Image resources: images with name "feature" (priority), "cover", "thumbnail"
3) Site.Params.images if set

Fixes #4349
