HOW TO: Batch Watermark Photos in Adobe Photoshop
Adobe Photoshop’s built-in automate function makes batchmarking photos a lot easier. If you happen to upload a lot of photos to the internet, follow the guide below to protect them from being stolen without due credit.
To begin, select one of your favorite photograph (make sure you save a copy of it before playing around with it)
1. Open the photo you wish to work with in Adobe Photoshop.
2. Click Window -> Actions or press ALT + F9 to bring up the actions window.
3. Click on the Actions tab on the actions window and select new action. The new action button is the second button from the right.
4. The new action window will appear.
5. The new action window will prompt you for a name, the set the action is under, the function key of the action and its color. Choose a descriptive name for your action. The function key acts like a keyboard shortcut key for your action. For our purposes, we will just set it to none.
6. Press Record. You will notice that the record button turns red.
7. The watermark can be created once Adobe Photoshop starts recording the new action. Create a new layer and use the tools (Window -> tools ) window to make your watermark. I colored my watermark text to gray as gray is both visible in dark and bright colors.
8. When you’re all done, click on Layer -> Flatten image. This will merge the two or more layers into an image so that it can be saved.
9. (THIS STEP IS OPTIONAL) Press File -> File Info and fill in your copyright information. Try to make this part as general as possible as it will be applied to all images when you automate the batch watermark process.
10. Click the stop button in the actions window when you are all set.
11. To automate the batch watermark process, click on File -> Automate -> Batch
12. Put all the images that you would like to watermark in a folder (It will be a good idea to backup these images first). Select the action that you would like, in this case Watermark. It is also good to check the Suppress File Open Options Dialogs and Suppress Color Profile Warnings boxes as they might disrupt the batch process.
13. You can also create a new action to batch watermark photos that are oriented vertically.
Enjoy!
reCAPTCHA
In one of my previous posts, I highlighted the use of images compared to traditional text as a better way to protect your e-mail address from Spammers.
reCAPTCHA brings this to another higher level. Instead of directly revealing the image file containing the user’s e-mail address, reCAPTCHA requires a person to successfully type two words in oder to obtain the requested e-mail address.
The image displayed below is one of the ways many websites use to authenticate that a person instead of a bot is completing a transaction through the internet.
reCAPTCHA, however, requires a user to type two instead of a single word for verification.
Why two words?
Besides providing its users the ability to hide their e-mail addresses from spammers, the image verification process is actually utilizing the brain power of millions in digitalizing books. A normal reCAPTCHA process goes like this:
A user is asked to type the two words. One of the words has already been solved by reCAPTCHA and reCAPTCHA has the solution to it. However, the other word has not been solved and this is where the user’s comes into play. By utilizing this method, this project aims to solve the imperfection of Optical Character Recognition tools that do not translate handwritten text to computer characters well enough.
The CAPTCHA Project
The CAPTCHA project is a project of the School of Computer Science at Carnegie Mellon. The project claims that over 60 million puzzles are solved daily using the brain power of people like you and me.
I believe it is only time that seperates us from digitalizing all the books available now. Preserving books in the digital form is more cost effective in the long run and most importantly, they will be accessible by our future generation.
Here is a CAPTCHA that helps me protect my e-mail address.

Yahoo: Ymail and the return of Rocketmail
Yahoo INC (NASDAQ:YHOO) just announced that they will re-open new e-mail accounts registration under rocketmail.com and its newly acquired ymail.com domain. This move is seen as a good and strategic one as the current domain (yahoo.com) is saturated with so many e-mail accounts that new users are finding a hard time getting hold of good names to start a new e-mail account.
It is a normal scenario for new users to pad their usernames with numbers such as davidleong2008 in order to register for a new e-mail account. However, Yahoo has not started the registration process for these two domains the last time I checked their websites.
Update : Yahoo has just started the registration process for ymail and rocketmail. Get your favorite login names before they are taken.
Protect your e-mail account from SPAMMERS
I have come across a lot of internet users who publish their e-mail accounts on their blogs or websites in the form of user [at] webmailcompany [dot] com. From my personal experience, 1 out of 3 personal blogs that I’ve come across use this method in the hope of avoiding robots that crawl for e-mail addresses. I highly doubt the effectiveness of such method. By googling *[at] gmail [dot] com, I managed to obtain 12 million e-mail accounts in 0.16seconds (The asterisk represents a wildcard character that accepts zero or more characters in replace of it)
Imagine what a professional spammer can do with 12 million gmail e-mail accounts! And bear in mind that we’re only talking about e-mail accounts that belongs to gmail. A simply Ruby or Perl script can extract all the information that google has indexed and replace every [at] with @ and [dot] with a period. A spammer would definitely be satisfied with this huge collection of e-mail addresses that Google has indexed and can now concentrate more on his malicious spamming activities.
Note that this also applies to *@gmail.com queries on Google. In fact, Google managed to return 99 million hits for this query.
A better way to protect yourself is to hand write your e-mail address and then embed it in an image file. At this time, most computers are not very smart in reading hand written images yet. Take this image and place it as a link on your website/blog so that users will need to physically click on it to view your e-mail address.
I used Windows paint to create this.
