[v1.5] Make use of thumb / link to fullsize when uploading

Okay, so when I was uploading a file and creating a thumb, I saw that it was being made, but I was never given any code of it. So, I wrote a hack that if a thumb is made, displays a link to the fullsize and displays the thumb instead:

[edit] This silly forum software was parsing my code. *rolls eyes* Go here: http://linked.viper007bond.com/wp15-uploadmod.php for the code. [/edit]

Hope this will be helpful to someone. 🙂
