What is the problem on uploading gif files to GrabCAD

It seems like i'm having a problem with gif animations. They don't look fine on the model's page. What would be the problem?
1st image is when i right click on it and click to "open the image on another tab" (it looks fine when i do it)
2nd image is on the model's page (it looks terrible)

I don't know if it will help Cemal as this is the site I use... Maybe it is worth a try
and I only render out 10 images on the turntable....
