I have a wordpress self hosted webmagazine site which have 700 posts. Some posts use medium size images and some use custom size images in between posts. How can I force all the published posts to use the full size images (original image size) instead of custom size, medium size images or large size.
After googling I came to a point that there are number of process to make the new posts use default settings but there is no such solution to already published posts.
I would recommend running a search and replace mysql function, through phpmyadmin or using the following plugin: https://wordpress.org/plugins/search-and-replace/
UPDATE wp_posts SET post_content = replace(post_content, 'oldcontent', 'newcontent');
And just run this to replace/delete every piece of html that wordpress inserts that contributes to it sizing (dimension before the image extension, height and width properties, size property)
You can allow the images to be as such on your backend. I mean we do not need to care about the size of saved images on the server. The issue only comes into play while rendering these images on a Mobile App or Desktop Browser.
So the variable sized images should be scaled to best fit its container. The image should retain its original aspect-ratio && make maximum use of its container. This approach however requires that the frame/container size is known before rendering these images.
I have written a image scaling algo here We can improve this algo further(if needed) or we can use a 3rd party API to scale the incoming images from server, before rendering them on the Mobile Device.
