How to make a gif with pictures in Vdub ?

[Music Fan]

Hi,
I would like to create an animated gif with 2 or 3 pictures (jpeg) which have the same characteristics.
Virtual dub can open one jpeg, but how to open several jpeg and export it in gif ?
I know how to export a video in gif with Vdub but not a series of pictures.
If Vdub can't do it, is there anoter free program capable of doing that ?
I'm looking for a very simple process if possible.
Thanks ;)

Rename pictures as Picture.001.jpg, Picture.002.jpg and so on ( or Picture001.jpg, Picture002.jpg, etc) . Open the first JPG file and Virtualdub will automatically load the next jpg files and treat everything as a movie.

Then use export to gif.

Thanks !
It works but the first picture's duration is not the same than the following, I don't understand why.
I chose 1 fps as framerate and infinite looping.
Same problem with 0.5 fps. The first picture is displayed very shortly, not longer than in 1 fps :confused:, though the following pictures last longer in 0.5 fps than in 1 fps.

edit :
When I export these pictures as avi, there's no problem, they have the same duration. So I wondered what would happen if I opened this avi and exported it as a gif ... same problem !:o Very weird.
