When you post, be sure to put a few search words in the "labels for this post" section at the bottom of the post creation page. For example, in the prior mushroom post, I typed in "mushrooms"...so now you can enter mushrooms in the search box on the blog home page and quickly find all pictures of mushrooms.
For this page I'm typing in wildflower, jack in the pulpit, jack, and April among others.
Be sure to at least include a general search tagline like "trees", "streams", "geology" etc.
Best to all.
