If you only have access to Photoshop but want to make a .gif, heres a quick tutorial:
1. Save your image sequence into a folder.
(eg. The folder "chewingSequence" contains: "chewing01", "chewing02", "chewing03" ....... etc ..... "chewing20")
2. In Photoshop go to "File => Scripts => Load Files into Stack".
3. In the menu change the "Use" from "files" to "folder".
4. Click "Browse" and find the folder where you saved the image sequence .
(eg. "chewingSequence")
5. Click "OK" and wait for the images to be imported.

imation".
