I made a simple script in javascript for displaying sprite sheet animations since I could not find any good tools to do it for me. I hope it might be of use to someone else too.
https://github.com/wulax/sprite_sheet_preview/blob/master/sprite_sheet_p...
The script assumes all frames in one animation cycle are one one single row. If a sheet has multiple rows / animation cycles, you can change row by clicking on the document.
For more instructions, read the comments in the script.
Example of the script running:

Note that the image in example, male_walkcycle.png, does not have a single animation cycle per row. The first one is stand/idle animation, because of this a small jump is shown in the walk animation.

If someone is interested in creating an animated gif from a sprite sheet, here is one way to do it using ImageMagick (available on most Linux distros):
Cut the sheet into separate image files:
convert male_walkcycle.png -crop 64x64 +repage +adjoin tile_%02d.png
Then join the images into a gif:
convert -delay 8 -loop 0 -dispose Background tile_*.png animation.gif
There is an image magic installer for windows as well. Even there is a portable version.

If you are using the DOM then you can get hardware accelerated animation by using css animations. Something to consider if you are not using a canvas and smooth animation on mobile.
