Hi @dracula_show!
Umm if you are using a fixed site, then the easiest and the most stable thing to get images reliably is just by fetching there page HTML with http and then use html extract content operation, so now once you have the extracted HTML you can try to fetch the CSS element targeting the image, as if you are using a same site every time this would be same, so just map that and there you will get the IMAGE URL or source, now you can either download it or embed it, as this might sound a little hectic but once setup this would be really great for 1 site. Make sure you have to find the specific section where it is stored to map it down further to extract the URL and information so that is the main work else everything will fall into place.
And for your output, just use a well defined structured system prompt with a good model like GPT-4o or higher and then attach a structured output parser for an extra layer of instructions and there you can specify the length and other parameters.
You can see this:
Also you can use EDIT image node to customize the images further.
