*********************************/
/*SoMe InFoS:
The index must be a number between 0 and 101
If you choose for example $thumb->index = "2", the Thumbnail will be as half as greate as the original picture
For savety is cared enough, because this class will work only with datas from the type image/jpeg or image/jpg
and it checks if the index is a number and between 0 and 101. If the variable picture is no image the script will
not work and end with exit(). If $index is not a number or not between 0 and 101 it will be set to 2.
Everybody can use this class freely and give it around, but with a note, so that everybody can see who is tha author and his E-Mail adress (Daniel Thul, hide@address.com)
If you use this class, I would like if you write me an E-Mail, because I would like to see if anybody uses my class.
Feel free to report me bugs or ideas for improvements. :-)*/
