    Find this line functions.php
    add_image_size('excerpt-thumbnail', 200, 140, true);

    200 is width
    140 is height

    After that run once.

    Hey there and thank you for replying, but that did not change the resolution.

    I am sorry, but I guess I forgot to mention that I use Post Thumbnail Editor for cropping the pictures for the Iconic One format (200×140).

    I added your code to the functions.php in my child theme and upped the resolution to 800 x 560 (4x) but the picture size is still 200 x 140 in “post thumbnail editor”

    The above code will work with our theme that you download from here, for the free version we do not provide support on custom child themes but only the theme you get from here, before asking for support please disable all third party plugins.

    Kindly ask plugin support questions in the respective plugin forum.

    You are completly right, should have thought about that before hand.

    For anyone gettig here via search funktion, I continued my inquiry here:

    Me again:

    I checked with the Plugin maker and (to be sure) disabled the plugin:

    Result still negative. The functions.php is modified according to your tip above and the excerpt thumbnails are bumped to 800×560. I erased the thumbnail several times in several articles, reuploaded the images and used regenerate thumbnails.

    Still the experct thumbnail on the main page are blurry and low res. (

    By the way: Do you have a tip on how to decrease the space between the main page post excerpts? Of course I could open a seperate thread for that …

    For anyone trying to modify thumbnail size in their Iconic One child theme use the following code in functions.php in child theme:

    You must be running Iconic One Version 1.4.2 or later for this to work.

    function iconic_one_child_thumbnails() {
    add_image_size('excerpt-thumbnail', 120, 120, true);
    add_action( 'after_setup_theme', 'iconic_one_child_thumbnails', 11 );

    After that run once.

    If want to modify directly use this

    Hey there and thanks for getting into it.

    I tried modifying the functions.php in my child theme. In the end it didnt help, but here’s what happens:

    1. I bumped the resolution to 4x (800×560) and it did in deed increase resolution just fine, but:
    2. Thumpnail regeneratior gave a error message and wordpress responded with a “couldnt modify header” message
    3. So I started over and tried it again. Second time all worked fine but now the excerpt thumbnails only get bigger not sharper.

    Any tipps?
