Technique explainer

Tilkie vs. right-click & screenshot blockers

These apps disable right-click, block copying, or claim to stop screenshots. Here is exactly how each block is bypassed, in under a minute, with no technical skill, and what to do instead.

How blocking works

These apps run scripts in the visitor's browser that cancel the right-click menu, intercept keyboard shortcuts, watch for the developer tools, or lay an invisible "shield" over the image. Some listings go further and say they stop screenshots.

There is one fact that undoes all of it. To display an image, the browser has to download it to the device first. By the time you can see a product photo, the file is already sitting in your browser. Every block runs after that has happened, so it is guarding a room whose contents are already outside.

Try it yourself: how every block is bypassed

Do not take our word for it. Every method below is something you can do right now, in under a minute, on this page or on any store running these apps. None of it requires any technical skill or any software you do not already have.

What the app blocks	How anyone gets the content anyway
Disable right-click	In Firefox, hold Shift while you right-click. The page's block is ignored and the normal menu, including Save Image As, appears. (Firefox honors Shift+right-click; Chrome, Edge, and Safari do not, so use one of the methods below in those browsers.) Turn off JavaScript in your browser settings, or open the page in reader mode. The script that cancels the menu simply stops running. Open the developer tools and remove the page's contextmenu handler, which restores right-click immediately.
Disable copy and text selection	Press Ctrl+U (Cmd+Option+U on Mac) to view the page source, then copy the text straight from there. Turn off JavaScript to restore normal selecting and copying. Open the page in reader mode, which strips the script and shows clean, selectable text. Search engines and translation tools read the same raw page, so the text was never hidden.
Block developer tools and inspect element	Open the developer tools from the browser menu before the page finishes loading. Type view-source: in front of the page address to read the HTML and copy every image link. Turn off JavaScript, which disables the detector that watches for the tools.
Stop image saving, drag-and-drop, or an invisible 'image shield' overlay	Firefox: press Ctrl+I to open Page Info, then open the Media tab. You get a list of every image on the page, each with a Save As button. Chrome or Edge: open the developer tools (F12), go to the Network tab, filter by Img, and save any image. Or use File, then Save page as, then Webpage Complete, to download every image into a folder. Safari: open the Web Inspector (Cmd+Option+I), open the Sources tab, and save the images listed there. The real image has to load to be shown, so the overlay sits on top of a file that is already on your device and reachable.
Stop screenshots or block the Print Screen key	Windows: capture with the Snipping Tool using Win+Shift+S. A web page cannot touch it. macOS: press Shift+Cmd+4 for an area capture, or Shift+Cmd+5 for the capture toolbar. These are operating-system tools. The website has no way to disable them, and they do not use the Print Screen key a script might be watching for.

And that is just the manual list

Those are the one-image-at-a-time methods any visitor can use. Anyone who wants your whole catalog does not bother with them. They point a site scraper, a dropship importer, or a headless browser that mirrors the page at your store and pull every image at once, scripts and overlays included. We cover that in catalog scraping and cloned storefronts.

Prevention cannot work, and selling it is worse

Put the table together and the conclusion is hard to avoid. A viewable image can always be taken, so preventing image theft is not something any app can actually deliver. The blocks do not stop a determined thief, and they do not even slow down a casual one for long.

An app sold as prevention is worse than one that does nothing. It charges for protection that does not exist, it gives a store owner false confidence so they stop looking for a real answer, and it adds friction for genuine customers who simply wanted to browse. The person stealing your images is unaffected. The honest shopper is the only one who notices.

What actually works: traceability and enforcement

If you cannot stop the copy, the only thing left that helps is making every copy traceable back to you, and being able to act on it. That is the whole idea behind Tilkie. It embeds an invisible watermark in your product images that survives saving, screenshots, cropping, and re-uploading, lets you detect a copy wherever it appears, and turns that detection into a Chain of Proof certificate for a takedown. It does not pretend to lock a door that has no walls. It makes the theft provable.
