Hai bitwit thanks for your replay,
but Sorry, I dont want that stuff, What I want is – My client says He doest care about cropping the image before embedding to his blog post, What he do is add new post-> open the editor add title, inside the post add some text add a image, that may be 1800×1000(he is the hero), ok so it really mess up layout structure, using css not a good idea here, because some times image will be distorted, so what i am looking for is Is there a way to show the uploaded images(whatever size it may be) in custom size( that i have predefined in functions.php) in front end.
simply – search for any embedded images inside post and display those images in our custom size not the actual image size editor uploads.
I think a filter on the_content() will make the trick, but no idea on how to do it
