Imagine access to millions of pictures all for the public to use, enjoy and share (can't alter) but you can benefit from some amazing photographers for FREE.
Flickr.com allows the user to designate the type "permissions" his/her photos will have. Not only can you use Flickr.com to host your own content/images/pictures, however you can browse through and search for keywords that relate to your need.
Take for example a popular park or recreation area. Flickr.com allows you to search your words, refine the search, review the accuracy of the images and to build a digital gallery player that you can share on other sites.
Below is an example of a SlideShow player created on Flickr with shared permissions from the photographers. Win/Win. They gain exposure and you gain access to photos of your parks (potentially).
My example I searched for State Parks, Iowa, Federal Parks, County Parks. They returned the results and displayed the Slideshow player. In the upper corner their is a button "Share" and it will display an option to obtain "Embed" code. It will look something like this;
<object width="760" height="560" data="http://www.flickr.com/apps/slideshow/show.swf?v=71649" type="application/x-shockwave-flash"><param name="data" value="http://www.flickr.com/apps/slideshow/show.swf?v=71649" />
<param name="flashvars" value="offsite=true〈=en-us&page_show_url=%2Fsearch%2Fshow%2F%3Fq%3Dcounty%2Bparks%252C%2Bstate%2Bparks%252C%2Bnational%2Bparks%252C%2Biowa%26mt%3Dall%26adv%3D1&page_show_back_url=%2Fsearch%2F%3Fq%3Dcounty%2Bparks%252C%2Bstate%2Bparks%252C%2Bnational%2Bparks%252C%2Biowa%26mt%3Dall%26adv%3D1&method=flickr.photos.search&api_params_str=&api_text=county+parks%2C+state+parks%2C+national+parks%2C+iowa&api_tag_mode=bool&api_media=all&api_sort=relevance&jump_to=&start_index=0" />

<param name="src" value="http://www.flickr.com/apps/slideshow/show.swf?v=71649" />
<param name="allowfullscreen" value="true" />
...Once you have this you can customize the display size and paste the code into the Page HTML Code where you want this to display. If you are set up with a blog, the default setting to create a post is "Rich Text". There is a tab right next to this labeled "HTML" generally that you click. Paste the code in where you want it displayed (a good trick is before you click the HTML tab, to place your curser on the page where you want it to appear. When you click into the HTML code your cursor should appear where you need it. Right click, paste and save.
It really is pretty easy. If you run into trouble or have questions, drop me a note and I'll be glad to see if I can help!
