You create an ideabook by clicking any of the pictures of houzz on the link that says "Add to ideabook." Mouse over the picture and the link appears in green. When you click it, you get an option to add it to an existing ideabook, or to create a new ideabook with a new name. You can also add notes to the picture to remind you what you liked about it.

So, if I find other people's photos on Houzz, or the web, that illustrate my theme, I can put them in an idea book, i.e. edible container gardening, even if I did not take the photo myself?That does not violate the copywriter laws?

The photo links back to the original source from which you obtained the photo. The ideabook is a way to save the photo for easy reference. To get photos from around the web, first download the houzz "Bookmarklet" .

Where do I find Bookmarklet?

Mouse over where it says "Your Houzz" at the top right of the page and click on "Get the Bookmarklet" in the drop down menu.

Thanks, groveraxle!
