Support » Plugins » Force crop to Medium size

  • Norke


    I have searched before asking. I found a few plugins and forumposts, but they aren’t working for 2.7 yet. I hope there might be a quick hack or maybe I missed a plugin or post.

    I would like to have 75×75 and 225×225 thumbnails (If it’s possible, I could also use 150×150 but I can use the 225×225 thumb for it.)

    I tried changing line 147 in wp-includes/media.php
    function image_resize_dimensions($orig_w, $orig_h, $dest_w, $dest_h, $crop=false) {
    function image_resize_dimensions($orig_w, $orig_h, $dest_w, $dest_h, $crop=true) {
    but I don’t think it’ working.

    I hope someone can help me on the right direction. Thank you 🙂

  • you don’t need to hack the code, you just have to change the medium size crop option from 0 to 1, which you can do from your functions.php file, or by writing a plugin.

    placing something like this inside your functions.php should do the trick:

        add_option("medium_size_crop", "1");
        update_option("medium_size_crop", "1");

    also take a look at this topic if you wish to add more image sizes to your wp installation.

    sorry, pasted the wrong option again, argh, should be:

        add_option("medium_crop", "1");
        update_option("medium_crop", "1");

    aesque … when I paste this code into a functions.php, I get an error … could you tell me how to implement this properly?

    EDIT: there’s a bracket missing in the first line. Should be

        add_option("medium_crop", "1");
        update_option("medium_crop", "1");

    Now if only I could find a way to do this only for landscape format images, and leave the portraits the way they are ….

    oops sorry about that 😮

    also, i’ve learned recently, it’s better to check an option’s existence with

    if(false === get_option())

    than with


    because the second version will also return false (equal to true, that is) if option is there, but empty.

    mores: i’ll look into it, it all depends on the order in which functions are executed.

    Thanks, for looking into the portrait/landscape thing and the info on the option-checking!
