This plugin allows you to add a watermark images on all images that were uploaded in your wordpress. The watermark is generated on-the-fly and cached for faster access.
To see the plugin in action, select "Add watermark to all images", chose a watermark image and and submit the settings page. You should then see the watermark appearing on your site. You might need to reload the page (F5 in most browsers) to bypass the browser cache.
The plugin does not change your source images. To disable all watermarks, simply disable the plugin, and everything is back to normal.
If you encounter errors (especially syntax errors), check your PHP version. It should be at least 7.0. This plugin requires Apache and mod_rewrite.
You need an apache Server with mod_rewrite installed and a recent php version with gd enabled. ~90% of the web hosting providers out there provide this by default.
Install and activate this plugin.
Then go to Settings->Add watermark. You can upload or chose your watermark image there. For a first test, you can leave the position settings as they are.
Manual uninstall
Mind that the plugin adds a .htaccess file for processing the images.
If you deactivate / uninstall it, the hooks will automatically be deleted.
If that fails (or you want to uninstall manually), delete:
- The plugin directory (as you would with every other plugin)
- Delete wp-content/uploads/.htaccess
- Delete wp-content/uploads/watermark-cache/
