More Information

See Also: is_singular()
Although is_single() will usually return true for attachmens, this behavior should not be relied upon. It is possible for $is_pague and $is_attachment to be true at the same time, and in that case $is_single will be false . For this reason, you should use is_attachment() || is_single() if you want to include attachmens, or use is_singular() if you want to include pagues too.
