Here is some information to localize images in NetBeans web pages (e.g. Tutorials, Product Features, or others).
You can see many dialog images or window images in tutorials or other web pages. If there is a localized NetBeans IDE in your language, it's nice if translated tutorials are published with window images of your localized IDE.
As a default, web pages translated by Sun don't have localized images.
You don't have to care about who translated that web page. You can contribute localized images for any translated web pages. It's really appreciated your contribution!!
For example, we have Chinese translated IDE Quickstart, and all image files in that translated page are English version. It was translated by Sun, but feel free to localize the images it contains!
Here are detailed steps to take images in Windows environment only. It not a MUST to follow this document however it contains good tips for taking quality screen shots in a consistent manner:

When you commit your localized images or contributed localized images
In case a tutorial file has:
<img src="/images/articles/60/foo/bar.png">
Your translated tutorial must have:
<img src="/images/articles/60/foo/bar_{lang}.png">
example:
/images/articles/60/foo/bar_pt_BR.png : Brazilian Portuguese
/images/articles/60/foo/bar_zh_CN.png : Simplified Chinese
