I recently had to resize an awful lot of images for a client’s site in order to improve their load time. The site is very image heavy, but some of these images were over 6mb, which has serious ramifications for SEO and general user experience, especially on mobile.
In today’s post, I’m going to take you through the solution I came up with, using R to resize the images to your chosen dimensions. There weren’t really any full guides to doing this that I could find on Google, so hopefully this is helpful.

- Bulk download a series of images
- Load them into your R environment
- Resize them to your specified dimensions
- Save the resized images
It’s basically the all-in-one image resizing function for R. Handy, right?

Having binged an awful lot of their crossover events over the last couple of years, I recently got to wondering which character had been in the most of them and, thanks to the brilliant Marvel API, R and a little patience, I’ve managed to find not just this answer, but a couple of other interesting ones too.
I had so much fun doing this that there may well be a few follow-up posts using the API, but today, I’m going to stick to the question that spurred this post: Which Marvel character has been in the most crossover events?

A big part of my job for the last few months has been updating my agency’s data protection policies and practices in order to get us in line with the forthcoming EU data protection law, known as the GDPR (General Data Protection Ruling).
