The GIMP

Every fall I teach an Internet development online course.  One activity in the class deals with creating simple graphics for web pages: banner, background, transparency, animated gif and graphical buttons.

These graphics are placed on a web site developed as part of the course.  I don’t cover specific use of programs: FrontPage, DreamWeaver, PhotoShop, etc.  The students are free to use whatever is available to them.  The web development side is never a problem.  I know enough about most HTML editors that I can help students through most problems that are unique to each editor.

Graphics are a different story.  Few students have a good graphics program or the knowledge of using one.  I can’t ask them to go out and buy a $70 copy of PaintShop Pro let alone a copy of PhotoShop.

This year I decided to try GIMP.  It’s a free, open source, photo retouching, image composition and image authoring program.  It is as close as you can get to PhotoShop without spending any money.

There was only one problem with my plan; I had never used GIMP before.  I was sure I had downloaded and installed it several times, but I had never spend an hour trying to use it to create something.

I blocked out a little time and dove in.  I was surprised how easy it was to do fairly sophisticated image editing.  Within two hours I had created all the graphics for the class activity.  On top of that, I felt good enough about my skills that I did an interactive session with my class and showed them how to use the GIMP.  I prefaced the session with, “I have only used this program for two hours, so I might not be able to answer questions about advanced use of the tools.”

It went pretty well.  I recorded the session in Elluminate so it could be reviewed as the students worked with the software.

The GIMP web site has many tutorials.  I reviewed some of them as I learned how to use GIMP to create an animated GIF (the only thing I couldn’t figure out on my own).  The tutorials are divided into Beginner, Intermediate and Expert.

For a free program, the GIMP is a great application.  Many of the processes used in GIMP are identical to those used in PhotoShop.  For a student, it’s a powerful program to learn the basics of image manipulation.

WIPO Does Copyright

The World Intellectual Property Organization (WIPO) has released its second “Children’s Guide” to copyright.  The title is Learn From the Past, Create the Future.

The book is appropriate for a student reading at the nine to twelve year old reading level.  There are good examples of what is and what is not protected by copyright, how copyright works, how long it lasts and how copyright is managed.

The document also explains plagiarism, piracy and other forms of copyright infringement.  There are sections that explain how different technologies (like P2P) can be used to violate copyright law. 

One nice section is the eight pages explaining public domain and the limitations of copyright.  There are lists of resources for free music, photos, movies and literature available in the public domain.  There is also a paragraph that mentions Creative Commons.

There are also games throughout the 72 page document so your little ones can play along as they read about copyright.  Here is a good activity to get them started. 

The document is available in the “free publications” section of the web site.  The second page of the document says “copyright WIPO 2007”.  Does this mean you can’t print the document for your students without permission from WIPO?

Five Minute Rule

One of the most common questions I’m asked in class is, “should I save this to my USB drive?”  I have never answered the question with anything other than an affirmative.

It boils down to the value of my time.  The last USB drive I bought cost $20 and it holds 2GB of data.  A typed page is about 2k if left in ASCII format.  A typed page uses about 0.00002 dollars worth (two thousandths of a penny) of space on my USB drive.

If my time is worth a few dollars an hour, it makes sense to save everything I take time to create.  I draw the line at five minutes.  If recreating something takes more than five minutes, I save it on my USB drive.  If it takes less than five minutes, it might not be worth getting the USB drive out of my pocket, plugging it into the computer, waiting for the security software to load, typing my password and navigating the folders to find the file.

Otherwise, it gets saved.

I Don’t Have Time

Things I have heard other people say:

I don’t have time to learn Google’s search operators (+, -, site, filetype, etc).  I can always find what I’m looking for in fifteen or twenty minutes.

I don’t have time to create folders for each of my projects and give my files meaningful names.  I can always find the file I am looking for in fifteen or twenty minutes.

I don’t have time to learn how to insert my digital pictures into my weekly newsletters for my students’ parents.  I prefer to get my pictures developed and then tape them to my newsletters before I photocopy them.  Wal-Mart has one-hour development and I can drive there in fifteen or twenty minutes.

I don’t have time to setup a del.icio.us account.  I can remember all the URLs that I need to visit.  If I run across something interesting, I email the URL to myself.  When I need it, I can usually dig through my email and find it in fifteen or twenty minutes.

I don’t have time to setup a flickr account.  If I want my family to see the digital pictures I have taken, I can email them to everyone.  We all have unlimited email space and it only takes fifteen or twenty minutes to send a set of pictures to everyone I know.

I certainly don’t have time for a full night of sleep.  I’m up too late trying to get everything done.

Yahoo Mapmixer

Here is a new tool from Yahoo that lets you add any graphic as an overlay on a normal Yahoo map. A slider tool lets you make the graphic transparent so the underlying map can be seen.

Mapmixer gives anyone the ability to easily place a graphic (I tried GIF, JPG and PNG) over the web 2.0 version of Yahoo’s interactive maps. The process takes four steps:

1 – Choose the city or location for your overlay.
2 – Upload your graphic.
3 – Adjust the size and position of your uploaded graphic so it fits the map.
4 – Tag and publish your Mapmixer.

This site has a lot of potential for educational projects.

To appreciate the above map a little more, check out the full screen version.
