What are some free programs that can help determine pixel coordinates for image maps?

Determining pixel coordinates for image maps can be a tedious task, especially when working with complex images. However, there are free programs available that can help simplify this process by allowing users to easily identify and extract pixel coordinates for use in creating image maps. One such program is GIMP, a free and open-source image editing software that includes a built-in feature for selecting and displaying pixel coordinates. By using the "Info" panel in GIMP, users can easily determine the exact pixel coordinates of any point on an image, making it easier to create accurate image maps.

// Example PHP code snippet for extracting pixel coordinates using GIMP

// Open the image file in GIMP
$image = 'path/to/image.jpg';

// Use the "Info" panel in GIMP to select a point on the image
// The pixel coordinates will be displayed in the panel

// Repeat this process for each point you want to include in your image map
// Note down the pixel coordinates for each point and use them to create your image map
