+
+This module allows you to add positioned images (such as watermarks,
+logos, or stamps) to PDF reports. Images can be precisely positioned
+using millimeter coordinates (top, left) and you can control whether
+they appear on all pages or only the first page.
+
+The module supports two types of images:
+
+-  *Company-level Images*: Define images at the company level that can
+   be included in reports by enabling the *Include Company Images*
+   option
+-  *Report-specific Images*: Configure specific images for individual
+   reports, filtered by company context and always shown when configured
+
+**Table of contents**
+
+.. contents::
+   :local:
+
+Configuration
+=============
+
+To configure company-level images:
+
+1. Go to *Settings / Companies*
+2. Open your company record
+3. Navigate to the *Report Images* tab
+4. Add images with position settings:
+
+   -  Upload an image - width defaults to 50mm and height is
+      automatically calculated to maintain the original aspect ratio
+   -  *Top (mm)*: Distance from the top of the page
+   -  *Left (mm)*: Distance from the left edge of the page
+   -  *Width (mm)*: Width of the image (changing this auto-adjusts
+      height)
+   -  *Height (mm)*: Height of the image (changing this auto-adjusts
+      width)
+   -  *Respect Image Ratio*: When enabled (default), changing width or
+      height automatically adjusts the other dimension to maintain
+      aspect ratio. Uncheck for manual control of both dimensions.
+   -  *First Page Only*: Check to show only on the first page
+
+To configure report-specific images:
+
+1. Go to *Settings / Technical / Actions / Reports*
+2. Open the report you want to customize
+3. Navigate to the *Report Images* tab
+4. Check *Include Company Images* if you want to show company-level
+   images in addition to report-specific images
+5. Add report-specific images in the list with the same position
+   settings as above
+
+**Note**: By default, images maintain their aspect ratio. When you
+upload an image, it's automatically sized to 50mm width with
+proportional height. You can then adjust either dimension and the other
+will update automatically to prevent distortion.
