Infinite Scroll loading .gif

Hi,

I have a lot of problems with the loading.gif picture which appears when i’m scrolling down. Even when I have deleted it from my ftp, the picture is still here (which I really don’t understand)…
I have also looked in the .js files but I haven’t found anything.

So I’d like to delete this .gif picture but I don’t know exactly how to do that.
For now, I found a way around and I set the number of article to 100 (no scrolling)…

aisemusic.com – I’m using wordpress 3.7.1, Marla theme 1.5.1, and the jetpack for stats.

Thanks and sorry for my English! 😉
