Just to preface, I have never used a crawler or scraper before in my life.
There's a neat feature on reddit where if you submit a link, it'll crawl the website, find the biggest image (or find an image with an open graph tag), shrink down the image and create a thumbnail with that image.
I want to do this on my website.
I'm making this thread because I want advice on how I could implement this. Is there a good package for this sort of thing? Will certain crawlers be better for what I'm looking for than others?
Finding the biggest picture on a website is a whole other case! You should probably collect all image urls on the page and fetch them one by one and see what image has the biggest size.
