I have Liferay Spring Maven portlet, and a liferay theme. Now user will upload an image through the portlet. How can we place this in /webapps/theme/images? Any inbuilt liferay feature/API which would help us place the uploaded image into the theme?

I would never change the file in the theme. What if your theme is in a WAR file? What about caching (usually the images form a WAR a cached in the browser)? What about security? You could upload the image into "Documents and Media" instead and include that one in the theme - that would be even easier to implement... – Tobias Liefke
@Tobian I dropped the idea of uploading the image to theme, since next time when we release new version of the same, the uploaded data will be lost. Instead I will be uploading the image to a directory on the file system and read it from there. – Seeker

For file upload functionality, you can refer: How to upload file in relative directory

For dynamic path of theme's image folder, you can get it through ThemeDisplay object as following:

Action:

ThemeDisplay themeDisplay = (ThemeDisplay) request.getAttribute(WebKeys.THEME_DISPLAY);    
String themeImagePath = themeDisplay.getPortalURL() + themeDisplay.getPathImage();

Where request can be renderRequest or actionRequest.

JSP:

<liferay-theme:defineObjects />

String themeImagePath = themeDisplay.getPortalURL() + themeDisplay.getPathImage();

Other relatively used options are themeDisplay().getPathThemeCss(), themeDisplay().getPathJavaScript() or themeDisplay().getPathMain();
