Well getting them organized and animated isn't going to be difficult. Using the animation in a video may be a tad problematic. Gif animations are created to run in emails and on websites. They are usually low resolution and small-sized. Elements won't animate files if they're too big. You can make yours and see how it works in a video - assuming you can find a gif to avi converter. The next time you get an overwhelming desire to do a good deed, use the open-source Synfig to do it;-)

There are a number of other free animation programs floating in cyberspace.

Open the jpgs you've created. If you've got more than 10 of them, don't open more than 6 or 7. Move the image that's #1 a little to the right (or left). click on the Move Tool, click on image #2 and drag it onto #1. Click on image #3 and drag it onto #1. Do this for all the images in your animation, drag them all onto #1. In the Layers Palette you'll see them all stacking up. Now for some tidying up. Right click on the first (the bottom) layer in the Layers Palette (Background) and click on Layer From Background - animations don't run if the first layer is locked and Background layers are locked. Before you do anything else save this file in psd or gif format.
Next, let's resize for NTSC animation. The standard NTSC video frame size is 720x480 so Image>Resize>Image Size. For now leave the resolution at 300. Make sure the boxes next to Resample and Constrain Proportions are checked. Change the width in the top box (pixel units) to 720 if your images are landscape orientation or 480 if they're portrait. Hopefully the other dimension will by close to what it's supposed to be. If it isn't, tweak one or the other 'til the dimensions are as close as you can get them to 720x480.
(For later, if needed: If NTSC sizes don't work, resize for normal gif animation. Image>Resize>Image Size. Uncheck the box next to Resample and change the Resolution to 72. Recheck the box next to Resample and, up in the Pixels box at the top of the dialog, change the width to something between 350 and 600 - whatever works for the design you've created. Click OK.)
Let's animate: File>Save For Web

I made a HUGE error in this screenshot: the box next to animate has to be checked. Select GIF format and the other boxes associated with it should change automatically. In the Animation section at the bottom, make sure "Loop" is checked. You can fiddle with Frame Delay after you preview. If you haven't gotten a message that the file is too big - yell "Yippee" and click on the Preview Button (#5). If it runs too fast, use a larger Frame Rate. When it looks like you want it to, click OK at the top and the Save As box will appear. Give it a different file name than the original (Jeff's Day Off becomes Jeff's Day Off Ani). Click OK and you're done.
If you get a File Too Big message. Go back and decrease the resolution. Image>Resize>Image Size. Uncheck the Resample box, try 200 first and, if you need to, decrease resolution until you get something that works. Click OK. Please don't forget to save the file with a slightly different name after each change you make.
If you get down to a resolution of 72 and it still doesn't animate, you're going to have to change the frame size. You can do that easily in the
Save For Web window.
Now, conversion...... Good News! If you have Windows, Windows Movie Maker will publish a gif animation to NTSC-AVI. I just tried it with one of my animations and it worked. Phew! Start>Programs>Windows Movie Maker Click on Import Media and browse to your animation. Drag it down onto the timeline. Over in the list in the left margin, the Publish To section. If you want to put it onto a friend's video, "This Computer" or DVD, etc. is probably your best choice. (In fact, you might be able to put your gif directly into the program your friend is using to edit his video.) In the next window that opens, select the third choice and choose NTSC-AVI and click OK.
Note: the animation I used had a transparent background which was black when I played it on Windows Media Player.
Good Luck!
