An image missing in all my themes

[Inge Jones]

According to my site error log, SMF or TP is looking for this image a lot images/icons/normal_post_sticky.gif   I don't seem to have it in any of my themes including default.

It is probably something from a mod you installed? I don't have that image either, but I also don't have the error.

Heres one stick that in your images/icons/ folders make your error log happy

I don't have any mods other than stuff I typed in myself.  But I am using Mercury theme if that makes any difference?

Thanks for the image
