472000 Replace images in HTML files - Easy job but I have no time

Hello :) I have 1 HTML template (eBay auction template). I have 247 items for sale and I need to use this template for each auction. In this template, it calls the same product image 3 times at the beginnging of the coding. I simply need someone to change the 3 images and save as an .txt file for EACH of the 247 products. For example, if the image is called [login to view URL], you will need to change the HTML code to call [login to view URL] (3 times in the code) AND save the file as [login to view URL] So, at the end I should have 247 .txt auction templates, each selling a different product. Need done ASAP.. next few hours! Thanks, Rob
