This is quite a simple project but it's very repetitive and requires thouroughness, precision and meticulousness. You need to be familiar with the Wordpress environment and image processing.
I have approximately 470 Wordpress articles that need to be defined with a featured image.
The job is to download the first picture from every article, crop/resize it properly to 1600 x 542px (with 80% quality) and upload it as featured image (but leave the original image on the page).
If the original image is smaller than 1600 x 542px, you will then resize to 780 x 264px.
If the page does not have any images but a video instead, you will need to take a good quality screenshot of the video and resize it to 1600 x 542px (or 780 x 264px as explained above) and then set it up as the featured image.
I look forward to receiving your propositions.
