What should be the file (folder) structure of images in a web site?
<p>I'm working on a project in ASP.Net that users can share photos about their trips. The users will have different trips, such as Tokyo - 11-01-2011, Sydney - 19-02-2012. So what is the best structure to store these images;</p>

<ol>
<li>Storing all images in one folder called Users Trip Photos. </li>
<li>Creating specific folder for each user's photos.</li>
<li>Creating specific folder for each Trip.</li>
</ol>

<p>My question is not just about this project. I wonder what should be the image structure in a web site.</p>
