Making animations for the web...

(using free tools!)

by Alan Zisman (c) 2002  - now in Polish!

The fancy animations you see on the web are made with expensive, hard to learn tools like Macromedia Flash. Smaller, simpler animations, called Animated Gifs can liven up a web page, and can be made using free tools.

Here's an example of an Animated Gif, taken from the anti-smoking website: Cigarette.com

Smoking skull animation

Animated Gifs are made out of a series of still pictures (frames), all with 256 colours, and the same size, saved in the Gif format. Gif animation software lets you arrange the frames in order, set the timing at which they will play, and whether they will loop forever, or just play once when displayed.

There are a number of shareware and commercial Gif Animation programs available at a range of prices... we're going to use the small, free, and simple: UnFREEz. If you don't have a copy, click on its name to download it (You will need an unzipping program to open it up-- there is no install; just double-click on the unzipped file to run it... note, however, that UnFREEz and in fact, this tutorial, is aimed at Windows users. Mac users may want to check out the freeware: GifBuilder (GifBuilder Carbon for OS X) or HVS Animator ).

When UnFREEz starts up, it looks like this:

To use it to create an animation, you need to create your series of frames, saved in GIF format, in some paint program, such as Windows Paint (which will open and save in Gif format if you have Microsoft Office installed), or higher end programs such as Photoshop. Alternatively, you could use KidPix or Windows Paint to save a series of graphic files in Windows Bitmap (BMP) or other format, then use a free graphics conversion program like Irfanview to covert each to Gif format.

When you have your frames, locate them in My Computer or Windows Explorer, and drag their icons, in the order you want them to be played, into UnFREEz's Frames window. When you're done, click the Make Animated GIF button, giving your file a name and location. (Hint: If you want to use your animation on the Web, don't use any spaces in the file name!)

You can experiment with the Frame delay setting to make your frames run faster or slower-- slower is more choppy, but faster may be too fast!
 

Viewing your animation

You may have noticed that the bare-bones UnFREEz program doesn't actually show you how your animation looks. You will need to view it in something else.The multitalented, free Irfanview works fine for that.
 

Making your frames in Paint

First, make sure that your copy of Windows Paint can open and save in Gif format. (If it doesn't, you can still use it to create the frames, using Irfanview or other software to convert from BMP format to Gif). Open Windows Paint (you'll find an icon in the Start Menu/Programs/Accessories menu)... go to the File/Open menu, and click to see the Files of Typedrop-down list... see if you have this choice:
Open dialogue box
If so, you're can proceed without needing any extra conversions. If not, go ahead anyway-- just remember, you'll need to convert your frames to Gif format (using Irfanview or other software) before using them with your Gif Animation software.

Before you start painting, pick a size for your animation. In general, smaller is better... small animations load over the Internet much quicker. In Paint, click on the Image/Attributes menu. You'll see:

Attributes dialogue box
Set your units to Pixels (picture elements-- dots on the screen)... just to give you something to judge by, the following image is 200 x 200 pixels (and is pretty large for an animated Gif:
Sample 200x200 pixels animation
Once you've set your size, feel free to create your first frame. Save it, if possible, in Gif format.I would suggest including a number in your filename to indicate which frame it is: Frame1.gif, for instance.

Here's a nice option-- once your frame is saved as a Gif, if you go back to the Image/Attributes menu, you'll see that the Transparancyoptions-- greyed out and unavailable in the picture above, are now available... checking the [  ] Use Transparent Background Color option lets you select a color-- anything in that colour will be transparent when the Gif is displayed-- that's a nice feature since it allows you to use that still or animated Gif on webpages with any background colour, and not see a coloured square for the Gif. Notice how that is used in the smoking skull at the top of the screen.

After saving Frame1, click the File/New menu item, to continue with the next frame. The Image/Attributes will remain the way you set them... though you'll have to re-pick a transparent colour for each frame. Obviously, all the frames in your animation need to be the same size. Aim to have at least a dozen or more frames to have an effective animation.
 

A note about saving in Gif format:

Gif format is limited to 256 colours. As a result, if you are trying to use a photograph as part of your image (whether a still image or an animation), when you save it as a Gif, the photograph will look less life-like. Look at the skull image at the top of this page-- at first glance, it may look good, but as you look closely, you may see how the colours were reduced.

(You can paste photos into your frames, and then draw on top of them, as was probably done in creating the smoking skull).
 

Conclusion:

Having to create frames one at a time in a program like Windows paint can be tedious... but using simple programs like this, and free software like UnFREEz, students or other non-professionals can create surprisingly effective animations. Just remember to keep them small! -- February 19, 2002
