What is "Lite Image Downloader" extension?

This extension is designed to download all cached images from the active tab directly to your browser's default download folder. Unlike similar tools, it doesn't re-download the detected images. This approach helps avoid common issues such as server-imposed download limits or CORS restrictions. Instead, the extension leverages the debugger API to request the already-cached binary data from the browser, then generates filenames based on the image URLs before saving them locally.

How can I use this extension to download images on the current tab?

First, ensure the extension's action button is visible in the toolbar area. If it's not, open the extensions popup interface and pin the extension for easy access.

To download all images on a page, navigate to the desired tab and click the action button once. The extension will scan all frame elements on the page, detect cached images, resolve their filenames, and begin saving them to your browser's default download folder.

Since this extension uses cached data instead of re-downloading images from the server, it avoids common issues like download limits or CORS-related errors that affect similar tools.

The badge on the action button will display the download progress. If you wish to stop the process at any point, simply click the action button again.

Can this extension replaces other image downloader extensions like "Download All Images" extension?

Not exactly. This extension uses the browser's debugger API to retrieve image resources that are already cached on the page. In contrast, other image downloader extensions may perform deeper searches and attempt to fetch images that haven't yet been loaded. For example, the "Download All Images" extension can retrieve higher-resolution versions by analyzing image elements and following their source references. This extension does not perform those additional steps.

However, downloading images from various websites often comes with challenges—servers may use CORS to block access, disable right-click functionality, or apply rate limits to image requests. This extension avoids those issues by relying solely on the images already cached by the browser.

In short, this extension serves as a complementary tool to other downloaders. It's recommended to try this extension first, as it is much lighter and avoids re-downloading. If it doesn't detect the images you need, you can then use alternative tools to fill in the gaps.
