Using 404 caching for local images
Almost all datafeeds contain links to images, located on the server of the merchant, a CDN or at the networks servers. You might want to host the images on your own server:
- A lot of external images might be a trigger voor google
- Sometimes the images are ridiculous large
- Even with images of decent size, resizing them using an image library like GD gives better quality then using html/css
Fetching the images during feed parsing is not a good idea, it will take a lot of time, and with a bit of bad luck the merchants server will block your IP for abuse. A better option is to fetch and store the images when needed with a technique similar to 404-caching
