You can search for specific images that meet your needs by using the "Search" ability built into this site. It's fast and easy to find exactly what you are looking for. Here is an example of using Search.
Let's say you need an image of the flint hills in the summer that has yellow and red in it. You would simply click in the search bar and enter; flint hills,summer,yellow,red
Note: I used flint hills in this example as two words flint hills. You can also enter flint hills as one word; flinthills. I use both in the keywords so both will work. Also note that descriptive words are entered separated only by a comma, No Spaces.
So in this example with those search words your results would be the example screen shot below. You can then click any image and go directly to it. If you want to return to the same search results just use your back arrow for your browser and go back so you don't have to keep entering the same search needs. You can do this with as many words as you want. With more specific search words your results will be more specific.
I will point this out. This is only as accurate as I have been able to make it. It works because I have "keyworded" the images when they were uploaded. I might miss certain descriptions that you are looking for so try alternative descriptions if you are having trouble finding specific images. If you are unable to find any images that meet your needs just drop me a note by the contact page and let me know, I might be able to help.
