How do I make a gif file with pics, or digital cam footage?

I wan to know how to make a gif image file for my wed pages with my pics, and recordings from my digital camera…

Please help.

Just save them as a .gif. Your photo editing software will do all the rest.

If the photo editing program you are using, perhaps one that came with your camera, doesn't support the saving as a .gif, you can download a number of free programs that will do the converting for you.

For still images there is Irfanview at http://www.irfanview.com/ although, with any program, photos are really better saved as .jpgs since they support millions of colors whereas .gifs only support 256 which sounds like a lot of colors, but it isn't for a photograph. All web browsers support .jpgs as well as .gifs.

For a recording, that is a moving picture, there are programs that will save part of a recording as an animated .gif, but I don't right off know of any free programs that do this and the result would be a humongous file which would take up a lot of bandwidth and webspace, that you will need otherwise.

You need to have your recording saved in a video format. That is a .avi, .mpg, .mov, or .wmv, if it is not already in one of these formats. It would help if I knew what format your recording is in and I could advise you as to what program you can use to convert; but, at any rate, try to get it converted into an .avi.

Then you can use the free program VirtualDub at http://www.download.com/VirtualDub/3000-2194_4-10783722.html?tag=lst-1 to edit any of the recording including taking a screenshot. Simply using "print screen" as a lot of Yahoo Answerers suggest on such things will not work with videos because of what they call the "codecs" involved.

Another possible solution would be the free program Alshow at http://www.altools.net/ALTools/ALShow/tabid/57/Default.aspx It plays most video formats, as long as it is not some kind of proprietory format of your camera, and you can use it to take screen captures, screen shots and save any audio as a .mp3.
