I Need A Photo Upload Script

I Need A Photo Upload Script
I need the upload script to:
1- Verify that the image is jpeg, jpg, gif, or png or convert image to jpg.
2- get image and resize it to about 300 pixels in width.
3- change file name to a random number about 7 digits long.
4- save it to a directory called uploads.
5- save the new image name to a mysql table(I know how to do this).
My server has the correct cmod permission.

Now I know that there are a thousands scripts out there that does this, I want one that works. I am not willing to pay alot for this, since most of you will simply search the web for a script and try to sell it to me. You are not fooling anyone. These are my terms.
