Changing post thumbnail size in non-responsive ColorWay

Hi,
I would like to resize post thumbnail on blog page in non-responsive ColorWay site.
Problem is, that I resized it, BUT, source of thumbnail is still in lower resolution, so, after I used custom CSS,

Code:

.content-wrap #blogmain img.postimg {
  width:500px;
  height:313px;

picture is pixelized.

I saw your responses for another questions, that people should change parameters in function.php

Code:

<?php inkthemes_get_thumbnail(xxx, xxx); ?>
                    <?php } else { ?>
                        <?php inkthemes_get_image(xxx, xxx); ?>

but there is no such thing as that. I found this only in blog.php, but after I changed those parameters, nothing happend.

I was using free version of ColorWay theme (responsive version) a while ago and there wasn't a problem with that. I found out that thumbnail there has source as

Code:

<img src="http://xxxxx/wp-content/uploads/2014/04/xxx.jpg" width="250px" height="160px" class="postimg wp-post-image hoverZoomLink" alt="" scale="0" style="opacity: 1;">

In ColorWay Pro i'm using now, source of thumbnail is

Code:

<img src="http://xxx/wp-content/uploads/thumb-cache/xxx-bd0fd5bb49231d21c571c1829c48e943-250x170-100-crop.jpg" class="postimg" alt="Post Image" scale="0">

so, i think can be a reason why my thumbnail looks like that.

Have you got any idea what shoud i change in ColorWay to make it work properly?

Thanks,

Sorry, but, again, nothing has changed. I mentioned about that i tried with blog.php

but even after I changed parametrs to, as you suggested 600x400, nothing happend.

 

Hello,

I think it is a cache issue, So clear your site and system cache.This will solve your issue.

I'm not sure about that, because thumbnails are hardcoded, so, even i'll clear site cache, they'll still there (tried few times). So, if i'll delete everything from wp-content/thumb-cache/ , thumbnails wouldn't regenerate. Also, if it would be problem with blog.php, all new uploaded pictures should have proper thumbnail, but they've not.
