I have small_image, thumbnail and base assigned for our product thumbnail images in the admin (which are visible there) which should be showing up on the frontend category pages. The placeholder images are being used instead. I gave the pub/media folder 777 permissions, flushed every cache despite being in developer mode and caching is disabled and that didn't work. I ran php bin/magento catalog:image:resize and received this error:
magento2/pub/media/catalog/product/b/f/bf-cover-fan.png" - original image not found
I am using the Mirasvit Optimiztion extension that does a number of optimization tasks like: makes webp images from jpgs and png, minimized JS and CSS etc...so not sure if this might be causing the issue as well?
