Its just too easy.
Whenever you uploading the model in Grab-cad library or workbench , there should a place in which the page asking for "URL to video"
Simply provide the URL to video and your animation will be live at Grab-cad model review section (Means in your model page).

And also lots of software is available free in internet, just google the photo to video convertor.
Use the software "Fun morph" for animated photo's.
Convert your photo animation to video, from the help of software like " Window movie maker " if you are using the Windows Xp and 7 than its available in programs.
thank you..I want to have photo animation in not video animation
If you want a photo animation than also you need the software to create it.
The animated photo will be the format " .Gif's "
for this also lots of software and free internet site available.
Just google it.
you need to create an animated .GIF file (not too large) and upload it as a render then set it as your default image.
the grabcad images are and aspect ratio of 5X7 and I would choose a lower resoution so the final file size is not too large.
Which software do you use to create the Gif's from the images????
Share it for getting easier.
I typicaly use Adobi photoshop but there are some web sites that will do it from an animation. I find it works best to choose a few renders (like 10) because some of the ones that I have made which are larger only work if you download the file and view it in a browser but do not show up in the GrabCAD preview.
