I use the 'PhpMaker' program to generate code for the backend of my site. Users upload images of real-estate and other things for sale. It works very well for me, but I'd like to add a function to it: to automatically resize images on upload. I'm not fussy about the parameters of the resizing. It can be to a certain size in kilobytes or height in pixels. The main thing I need is to have the large size of the uploaded file reduced to a web-friendly size of around 50 to 75 kilobytes.
I'm not a programmer, but I believe there is one file that is generated by PhpMaker that controls the functions of the upload, unique file names, etc... I'm wondering if the resizing function could simply be added to it. I'm attaching this file, called '[url removed, login to view]' for your reference.
