Intellij IDEA Apache Tomcat. How to edit images?

I'm learning web programming on Java and encountered a problem. I use Intellij Idea with a plugin

<plugin>
   <groupId>org.apache.tomcat.maven</groupId>
   <artifactId>tomcat7-maven-plugin</artifactId>
   <version>2.1</version>
</plugin>

to run local server and test my code. The thing is I don't know how to edit my images. I use

<div align="center"><img src="Images/logo.jpg"/></div>

and it works fine, but when I decided to change the size of my logo and recopied it to my Images folder Tomcat doesn't see the changes when he stars up. I get the same size jpg as I first copied it there. I think I know what's the problem. My guess is that Tomcat copied it somewhere only once at the first run and doesn't care about any changes in a file with the same name at each next run. He just using the "old" version. But the thing is I don't know how to make him recopy (or something) this file, or any file. Also I couldn't find the path where he stores it to delete it manually and force him to get the "new" version in such a way. Maybe someone can give me an advice?
