The watermark is placed on your images through a htaccess and php file. This means that your images are actually not modified. You can still download them from your FTP, and they will not have any watermark.
It applies the watermark on new images as well as images already uploaded. It does not alter your original image files.
By deactivating the plugin, the watermark will be removed on all images.
You have to know that :
- you need to be able to create a htaccess file in your uploads directory.
- you need the GD library.
- you need the Apache module «mod_rewrite» to be activated.
- works only with JPG files (for now).

- Activate the plugin through the ‘Plugins’ menu in WordPress
Note : GD library is needed and being able to create a .htaccess file in uploads directory.
- Can I remove watermark after it was added ?
YES, you can ! The watermark is applied in a way that doesn’t modify your original picture. By deactivating the plugin, the watermark will be removed everywhere.
- I deactivated the watermark plugin but I still see the watermark on my images, what’s wrong ?
It’s due to cache. Your browser keeps in cache your images. You should empty your browser cache and try again to check, it should solve the issue. Your server could also cache images with the watermark, try to empty the cache of your server too.
- How can I add watermark to pictures that were uploaded before the plugin was installed?
Once the plugin is activated, the watermark will be applied in all your pictures following the settings you chose previously.
- Does it alter my original image files?
No, it’s impossible. The watermark is applied dynamically thanks to a PHP script. The image files are never modified.

Was not transparent on a png. Didn’t have a scale feature and when I loaded a really big image it damaged the image view in media area. I tried it again with a small image and then edited a image. When I got done it looked horrible. I deactivated it and deleted it. The image was damaged and I had to start all over again.
quick support and goodwill
I installed the plugin upload watermark. Everything ok except watermarks was also appearing on my homepage under posts pictures on homepage. So then i decide not to use it and deactivate it. What a surprise that watermark didnt disappear from homepage pictures as it should.Probably some compatibility issue with wordpress 4.4.
only JPG… no pNG
I upload the image to be displayed and it doesn’t display on photos….

- The Plugin is now using Oriented-Object syntax. It needs at least PHP 5 to work correctly.
- Previous htaccess will not be merge with the htaccess of this plugin. It will be renamed so, if you have any problem deactivating the plugin reactivates the old htaccess file.
- The watermark.png file per default is now generated by php.
- Images with parameters (ie: picture.jpg?key=value&key2=value2) are supported but can generate issues. Dots in parameters are not allowed for security purposes.

- To activate these features, I recommend to click on update in the plugin page.

This version will fix this major issue.
If you were using version 0.2 or 0.1. Please save your watermark image to be able to re-upload it in the new version. This problem will not happen in the future.
- Added a direct setting button to the plugin which appears in the plugins list.
- Do not erase a previous htaccess file in the uploads directory, but merge both content.

Now, it is applied correctly.

- Initial release
