Blog Image Size (Change,

Hi Enfold Team,

I hope you can help me or give me a hint:

I want to edit the default Blog Post image (contributory picture), just read many threads and try to edit the follow code line
$avia_config['imgSize']['entry_with_sidebar'] = array('width'=>845, 'height'=>321); edit to 800 x 600

after that I use a plugin to regenerate thumbnails (plugin – https://wordpress.org/plugins/regenerate-thumbnails/)

but that is not working the images have not the size I want to display and edit.
When I use the Investigate abilities of my browser they have this size:
left: -5px; top: 0px; overflow: hidden; display: block; height: 556px; width: 843px;
But my edit is 800 x 600

Also I try to choose different sizes in the Blog Style. But that do nothing.
In my opinion, when I edit the image size of the blog “Select custom image size for preview”
the image of the Blog Post must have the size I choose? Or is the function for something else?

And what about the WordPress Media-Size, is there a edit to do or can I stay at default settings?

—
I want a Blog Size Preview Image in format 4:3
for example 800 x 600 and the image from my mediathek should stay in there without a crop.
Is there a automatic size when I choose entry with sidebar for the image size and the white space etc.?

I hope you understand what I want and can help me.

Thx a lot and have a gerat day
Tobias
