You wrote your post and you want to embellish it with nice images so that people will enter it and not just buy it.

You choose from google images a nice pizza spinning because you thought it was nice, it doesn't have to do with the post but it's nice and you don't care about it.

you add it to your post and publish it BUT IT DOESN'T SPIN, WHY DOESN'T IT SPIN?

Well my friend, you just copied or added to your post a .gif, an image that moves but in some sites is not compatible and only remains as a sad image of a pizza that does not rotate.

I don't know if this is a problem with my pc or how I upload the image but if this is really the case you could add support for .gif images.

There is also a .webp format that can move but I haven't tried using it, maybe that would work but would you want .gif type images on BBS? or if they already exist what is their format and how would they be added to the posts?

Although you could save the .gif and use a converter to convert the .gif to a video format

I just made the post and added the image to finish but I just saw that it does move. Now the post is a joke :c
I see it like this in the edit of the post, hopefully it will keep moving when I publish it.
