1. Google Images
"Oh, no..." I can hear you thinking it. In reply, I say, "Oh, yes!" Go to images.google.com and search something pertaining to the kind of story you want to address. For action/adventure, some great search words are armor, sword, dragon, gang, knife, police chase, ... so many things! If you think about it, people think in images. If you closed your eyes right now and concentrate on your favorite food, your mind would come up with a picture of that food, not the spelling of it in words. Images can be powerful at jogging your mind and inspiring you to continue with your story.

2. The Writer's Cramp
If you have never visited, please do! Sometimes, stepping away from your story/novel for a moment and participating in a quick thing that is different from what you were originally working on is just the right medicine for your muse. The Writer's Cramp is a great way to do that, because it is a one day prompt - so you can't get stuck on it for days. Either you do it, or you don't, and then they move on either way.

3. Writing Prompts
Under "Writing.Com Tools" on the left side, there is a topic called "Writing Prompts". It is awesome. These are prompts submitted by members of WdC, and you can totally filter through as many as you want until one completely inspires you. There are also some that are split up by genre, which is great when you are trying to find something more specific to your style.

4. Search Feature
Now, the topic here is very not-specific, but the great thing is, your search CAN be very specific. You can pick a certain genre *coughactionadventurecough*, the type of item you want (static, contest, etc), and read away. While I do not condone copying someone else's work, finding inspiration is a completely different thing.
