98362 Zen Cart modification required

This a quick and easy project for someone who is an expert with Zen Cart. Here is the specifications for this project. In the admin area where you add a product, it gives you an option to upload a picture of the product. I prefer to have an option so I can link to a picture (on another site of my choice) of each product rather than uploading one. That's all I need. The Zen Cart version I am using is 1.35 with the fix. There is no access to my server so you will need to complete the project and send me the file(s) so I can test it out on my server. Once it is confirmed to work without any problems, I will send payment by paypal. As mentioned, this is a straight forward, and easy project for someone who's familiar with Zen Cart which can be completed very quickly. So this project is for Zen Cart experts only. Thank you and I look forward to dealing with you.
