This is the terrible way I have "copy-pasted-developed" a code to upload some pictures, rename them and create thumbnail. As you will see is pure rubbish, but it works...
There should be a way to do it more trendy by calling a function, but this is too much for me (and this too: <? echo "I'm a nerd newbie"; ?> ) but trendyness let me sleep quite well so, the problems are:
1 How to check if they are jpg or not.
2 How to allow user uploading only 1 or 2 instead all.
The code dustman
