Permanent Watermark with GD2

[Sammy]

I have looked script for watermaking images permanent, not on the fly.
Becouse have'nt find any, I decided to try making one.
I'm not good on PHP (or ong english writing), but hope that maybe someone like to test it also.
There maybe many bugs, but I have used on couple hundred images with out problems. I dont take any responsibility, if this code messes your server or images, so be careful  :roll:
And Big thanks for DJ Axion, whose script I have used as base of this script (with util, and picmgmt.php)

REMEMBER to take backup from all files that You are modifying

I have modified util.php, include/picmgmt.inc.php and lang/yourownlanguage.php (finnish.php on my situation)

1.
Lang/finnish.php (english or whatever languageYou are using)
Add new line after line 984 (text):

        'select_album' => 'Select album',
Paste theese lines:

        'watermark_both' => 'Original and resized images',
        'watermark_wait' => 'Watermarking images...',
        'watermark_continue_wait' => 'Continuing to watermarking originals and/or resized images...',

2. include/picmgmt.inc.php

If everything has been done fine, You can now add watermarks on albums by going to "Resize Pictures". there should be new section: "Add watermarks". Just select imagesizes You want to be watermarked, and at the bottom of page, select album what You are going to watermark images in.

There should also be .PNG image "called logo.png". In my case, logo.png is on includes folder. If your logo.png is 30% trnsparent, then You get transparent watermark
You should also change the full path to point correct file (logo.png, or what ever Your watermark image is called)


Hope that I remember to put everything in it :?

[Ravage]

Great job! Will try it out later.

[Zcaithaca]

srry if this is a newbie question but where is the resize image thing located?

[Sammy]

srry if this is a newbie question but where is the resize image thing located?

When you are logged in as an admin, the script has two modes of operation : Admin mode & User mode. You switch between Admin & User mode by clicking on the corresponding link in the menu bar at the top of the screen.

When you are in admin mode, you can administer your gallery and the following menu bar appears :
(https://coppermine-gallery.com/forum/proxy.php?request=http%3A%2F%2Fcoppermine.sourceforge.net%2Fimages%2Fadmin_mode_bar.gif&hash=dde079dcd50258d68959d663e3fd5aa90a74a25a)

Resize Pictures is located on menu bar. It is not showing on above image, becouse ist from an older version of Coppermine, but it is between "Batch add pictures" and "My profile" buttons.

[Casper]

Addition to above, the link is not shown in the hardwired theme.

[Zcaithaca]

ok thx im using the hardwired so ill change it

[photoman13]

anyone have a sample gallery that is using this? for us to see?

Will the watermark covert the full pic? or is it just on a corner of a picture?

Thanks

[Sammy]

Here is one gallery where I'm using it.
http://www.jarnokalliomaki.com/index_carry.shtml

There are sometimes pics with out watermarks, becouse pics are added after watermarking that album.
You could ofcource move images to some temporary album and watermark pics in there. that way You do not get Your images watermarked many times and loose transparency of watermark.

On the other albums there are also watermarked pics done by Our old imagegallery, but most of watermarks are done on old gallery with imagemagick.


I will try to add same watermarking on "batch add pictures" page, so I get all new images automatically watermarked, while waiting CPG 1.3  

[Sammy]

Will the watermark covert the full pic? or is it just on a corner of a picture?

Watermark will convert ful pic.
It will be on corner. You can decide corner You want, by changing it on include/picmgmt.inc.php .

[Tarique Sani]

Can you zip up the relevant files and post a link OR sent it to me

I will incorporate it into the main CPG (of course your name will be in the credits)

[Sammy]

Hello Tarique

Here is link to zip
Permanent Watermark with GD2

This link will work for now, but I'm doing some changes on my website, so I dont know how long it will be there. But at least for couple weeks.


You could possible do some check on those code changes. I think there are some duplications on variable names on watermark_image() function on /include/picmgmt.inc.php.

[Tarique Sani]

Thanks - I have got the file, will look into the code and incorporate accordingly

[photoman13]

Sammy,

awesome coding there.. I got it working on 2 of my galleries

question: so now that it's installed... whenever someone uploads a photo is it automatically 'watermarked' or do we always have to go in and do it manually?
Sorry.. I haven't had any new photos to test that on... and thought I would ask

Thanks again for the code.. it was easy to install

As for the Hardwire theme, it was still easy to do, just changed the theme back to default and did the resizing (watermarking) there.. then changed it back when I was done

[Casper]

@photoman,

you don't have to change theme, just type in the url direct, i.e., yoursite.com/gallery/util.php

[Sammy]

Sammy,

awesome coding there.. I got it working on 2 of my galleries

question: so now that it's installed... whenever someone uploads a photo is it automatically 'watermarked' or do we always have to go in and do it manually?

It does not add watermark automatically  :cry:
I'm trying to get it work automatically when adding new pics, and if I succes in the process, I'll post code it here.


If You do keep albums, where You are adding pics, You need to create some temporary album, where to upload pics and watermark those in that album and move all images after watermarking to desired album.

If You Just add more pics to some album and watermark pics there, Your older (allready watermarked pics) are going to loose some of quality and transparency of Your logo.png watermark, becouse it just stamps watermark again in all pics.

[photoman13]

thanks Sammy

I'll just do it that way til you get that process complete

it's still a great addition

[Sammy]

Sammy,

By the power of friday Sauna and cold beer after it, here it comes...

First I need to say: This is NOT tested yet with couple hundreds of pics, but only few test images.


1
You need to add all modifications mentioned on this topics 1st and 2nd post.

2
Open Your modified /include/picmgmt.inc.php and find line 34. It should look like this:

Code Select Expand

               return false;

3
Add theese new lines after line 34

Code Select Expand



                //Adds watermarks to new images
        if (!watermark($image))  //this is for full size image
            return false;
        if (!watermark($normal))  //this is for intermediate size image
            return false;

Thats it.
Now You have watermark automatic

Just to make it sure, Your first 42 lines of code should be look like this:.

PS.
Remember to CHMOD every pic uploaded with FTP to 666, or You'll get some errors becouse You have not give apache/PHP right to save modified pics.


Tarique
I will change the zip file for You, but I will do it on monday, when Im on work

[photoman13]

Hey Sammy

good work

I'm gonna go test that myself right now

I'll let ya know

[photoman13]

awesome Sammy.. it works for me

Thanks again for this great mod!!!
