Script that takes a source image, resizes and renames the image, shows it online but doesn't store it in the server -- for aboodnour

I need a simple script where: 1. Using the code, I include the URL of the image (source) 2. I can set in the code (manual input) the image size (percentage, or width and height) 3. I can set a "file name", so the script creates an output image file with that file name. 4. The image file (output) is not stored in the server. Example: I have [login to view URL] I put the code like this (this is a madeup example): showimage ("../anyfolder/[login to view URL]",80%,[login to view URL]) The code is telling a) where the file is and which file b) to be resized 80%, the filename to use. The output will be [login to view URL] (in this example) and it will not be stored in the server, but will be shown in the browser. The only issue I find is when search engines (or users) want to search for the image directly, and they won't find anything. ([login to view URL]) I need to create multiple image files, and I don't wish my server to fill out with duplicates, where the only thing that changes is the size and filename.
