OK...to solve this for those who lack reading comprehension....

Here are the Thumb Nail Rules as posted.
I will explain each sentence .

TTENTION: EFFECTIVE JANUARY 24, 2007, New Thumbnail Policy  

**No Nudity/Violence in thumbnails, please read information at the above link

This I would hope is self explanatory

If you fail to upload a thumbnail, our system will auto-generate one for you,

What this means it will generate a thumbnail sized version of your original see next statement

which is a minature of your image.

If your image contains nudity/violence, *you must NOT use this feature;

• Please note the next statement

*you must upload your own non-nude/violent thumbnail.

Clear now?**

 

Once in a while I look around,
I see a sound
and try to write it down
Sometimes they come out very soft
Tinkling light sound
The Sun comes up again
