[TYPO3-english] Temporary Images

[Simon Nute]

Hi, I have searched the newsgroup but not able to find any information 
on Temporary Images.

I have a very simple site with a logo file in the template (TV).  I 
wanted to make some changes to the logo and so reuploaded the image.  I 
cleared the cache but nothing happened.

I then looked in the typo3temp folder and noticed that there were many 
many copies of my logo image.

Why does this happen and is there a way to turn it off please?

Many thanks for your time.

Simon
