Hi all anyone got an idea of how to create an animated gif using  
images uploaded in paperclip?

OR

some way to display rotating images in rails.

(i’m trying to create rotating sponsor images on the fly from user  
uploads)

Thanks,

Shawn

You don’t need to make animated GIFs for that. All you need is  
JavaScript.

Here’s a fine example of rotating images with a nice cross-desolve  
effect. No animated GIFs and no Flash necessary:

If you want to go onto the animated gif direction, i believe the only  
option you have is to look at ImageMagick and RMagick, but this is not  
trivial stuff.

On the other side, Javascript and modern browsers (like Safari and  
FireFox) can help you with something like :

a=0;  
setInterval(function(){  
a++;  
var d=document.getElementById(‘YourImageId’);  
d.style[’-webkit-transform’]=‘rotate(’+a+‘deg)’  
d.style[’-moz-transform’]=‘rotate(’+a+‘deg)’  
},15)

Hope this helps,
