Fix low image quality on iatistandard.org homepage

[mollieodsc]

The news post images at the bottom of the iatistandard.org homepage show as very low res.

e.g.

However, on the news landing page the image quality looks fine.

e.g.

Would it be possible to take a look at the image settings to give a cleaner, more polished look to the homepage? Ideally, the images would be as high-res as is feasible to give a more polished look.

Happy to provide more details if needed.

Thanks so much!

They are using a scaled 220 image on the home page. On the news page, they are using a scaled 880 then 440 (or something like that).

I think we just make them all 880, should have minimal impact on page size.

Looks like iati/context_processors.py has 3 variables that are what's relevant here:

• iati_news_sizes is used on home page
• news_featured_sizes top of news page
• news_list_sizes rest of news page
