Convert NFO/TXT file into an image file

I have an image hosting, which is using Mihalism Multi Host script. What I want to have done is an extension to this script. Make it so that the user may upload 2 more extensions, ".nfo" and ".txt" Whenever the user upload either nfo or txt file, the script should automatically convert them into an image file with PNG extension. Please see the attach file for the example of NFO and the image file (the example is GIF, but the script should make it PNG). The text font and size should be exactly as the given example image. In the admin panel, there should be 2 new options: - Use watermark (on/off) - Watermark Text (text input) If watermark is turned off, then NFO/TXT should be convert into the image file as the same way it came. (see [login to view URL] in attachment). However, when the watermark is turned on, the script should add 36 pixels height of white space to the image tail, and print the watermark (as set in admin page) into the middle of that space. See [login to view URL] in attachment file to see what I mean. This project should not be very hard, so please place a reasonable bid.
