I like to solve my own issues, with my own code (or at least partially my own code).
I've built a Laravel package to render commonmark files with frontmatter as static pages before. But with the Core Web Vitals becoming a ranking factor, the regular image-tags didn't meet the requirements anymore.
Another package had to be built 💪️ to add explicit
height to my images. The idea for the "SEO images for phpleague/commonmark" package was born.
To make actual use of it, I had to resize numerous images that were already part of my blog. But I wanted only the images that were too wide on regular.
Not being keen on manual work, I've opted to use PHP for the job once more:
php -r "echo getimagesize('https://rankletter.com/assets/blog/articles/keyword-cannibalization/example-for-keyword-cannibalization-min.png');"
To explain what is happening here:
php -rruns the given PHP.
getimagesizeloads or fetches an image and returns the dimensions of the image. The first element of the list (selected with
at the end) contains the width.
echoreturns the result and prints it out.
This in combination with the
find command allows selecting images based on their respective width.
Looking for the height? If you are after a certain
height, you can simply tweak the
Please note: There might be cases where this fails or returns 0, you should always check if your output is sensible.
