[Plugin: Simple Image Sizes] Bug: home_url() should be admin_url()

There’s a bug at line 44 in class.admin.php that is preventing the image regeneration to work when the “WordPress address (URL)” setting is not the same as the “Site address (URL)” setting.

Currently:
‘ajaxUrl’ => home_url( ‘/wp-admin/admin-ajax.php’ ),

Should be:
‘ajaxUrl’ => admin_url( ‘/admin-ajax.php’ ),
