Thumbnail size on home page

Hi!

Thumbnail sizes can be changed in functions.php where it says:

// Thumbnail sizes
add_image_size( 'thumb-small', 160, 160, true );
add_image_size( 'thumb-medium', 520, 245, true );
add_image_size( 'thumb-large', 720, 340, true );

And after changing, regenerate thumbnails.

Preferably you would do this with a child theme, and move the whole alx_setup function into the child themes functions.php and edit the values there.

Thanks Alex! Do you have a solution for fixing the ones that appear in the main column that shows recent posts?

Does anyone know how to change the thumbnail size in the middle column (main content area)?

The featured large image is thumb-large, and thumb-medium is used for all the other ones in the content area.

When I try changing the thumbnail sized via functions in my child theme, I just end up with the coding displaying as text above my header.. =/

Please see the documentation section “Child Theme” here. You need to copy over the whole alx_setup function (more on that in the docs)

Hi Alexander, is there a way to avoid image been cropped instead of resized? I realized that squared images are cropped to reach the rectangular size specified for the thumbnail.
thanks in advance.
