There are two types of themes with which a developer may be working when using WordPress themes. He may use a parent or a child theme. In WordPress, there are different functions that can be used to get paths to files, when using one of the above themes. Sometimes, finding a path can be difficult, despite visiting and revisiting many directories. Especially when you are modifying your WordPress site, not knowing where to find your files can be annoying. The following functions help find those paths in a quick manner.
The template functions can be put to use when resources are not overridden by a child theme. The following function is used to retrieve the absolute path to the directory of the current theme.

Finding file location for images
Another way of finding paths for images is by locating the images on the Media Library that is found in the WordPress admin panel. The full URL of the image is visible when selecting and clicking on the image. It is also possible to find image or file locations by using the inspector of elements. Though the above steps look simple, many beginner developers on WordPress finds it difficult to locate paths to files and directories, due to lack of knowledge of these easy functions.
