Melanie, another idea is - you could post them in the idea's section and they could show up as articles. Then you can work on it at your leisure or make it a series of articles of various host plants for various species. Plus, with articles, you will get acorns for all of your hard work.
And like Natalie suggested, you can just ask if anyone has a picture of a certain plant that you need for your article.
The articles will be listed here on this forum for easy access.
