Hi, thank you for try, but did you try make and use a child theme? I understand it as you did not. – Yes, you see the picture twice in that scenairo you described. Thats normal. The “fix” code is needed only for child theme. If you would be so kind to try it as I decribed, I would appreciate it. I did try almost everything (including disbaled all plugins). Thank you. Also, its concerning WP 6.9. You must manually allow the attachment pages if you are on fresh install. Attachment pages are disabled on fresh wp installs, but on already existing(only updated to 6.9+), they are normally available. Maybe it is due to this, as far as I understand WP is using featured image as content on attachmnets for wp 6.9 (but not sure)… And generally, yes, attachment pages are very useful, if you need content around your image. There are plenty use case. I dont understand the WP treat them as legacy…

closing tospics, there was a Mistake in my function file. Sorry and thank you all! Its fixed.

Very Interesting partial result!!!
I had to comment out part of code becose it is not cropping thumbnails at all! Explanation in comment:

add_theme_support( 'post-thumbnails' );
//set_post_thumbnail_size( 180, 180, true );  // not works with cropping setted in media backend!!!
add_image_size( 'related', 150, 100, true ); //related , must regenerate thumnails after

Unfortunatelly Im still facing wrong dimension issue…

actually thinking about _wp_get_image_size_from_meta which i think takes image size from image meta someway… Im stuck dont know where to track it…

even I made several sizes like in screenshot that works as you can see on printscreen, even default thumbnail have 180px… but still in <img tag on main page http://www.danielkral.cz/clanky have 100px dimensions:

<img width="100" height="100"
src="http://www.danielkral.cz/wp-content/uploads/K9mailLogo-180x180.png"
class="attachment-100x100 size-100x100 wp-post-image"
alt="K9mailLogo" title="K-9 email"
srcset="http://www.danielkral.cz/wp-content/uploads/K9mailLogo-180x180.png 180w,
 http://www.danielkral.cz/wp-content/uploads/K9mailLogo.png 300w"
sizes="(max-width: 100px) 100vw, 100px">

I found today somethimg could be linked to my issue (maybe not becose there is AJAX used): http://wordpress.stackexchange.com/questions/42860/wp-get-attachment-image-returns-different-image-size

Now Im searaching for the function which is responsible for wordpress that gets the image dimensions to check it, actually have not found so if you know please share… thx Im probably close cos im rewieving wp_calculate_image_sizes function and theirs variables…

Actually i can get rid of the dimension atributes on image even I can filter classes but I do not want to do it, I want to know why Im getting 100×100 image size on image with other size…

Thanks, I have this issue only when using excerpt on my main page, in single page even it is original thumbnail its resized corectly because ut was setted in media setting on backend… so this, Its happening on main page when using excepts.

Also i observed that issue is gone, when switch to other template, so I will have to check my function file…
Thank you, but I do not uderstand to it much, even if I did put your code the image appears in position I putted the code, so its totally wrong… you code should only change the value of variable not the print image…
I did read it before I wrote here… Im solving it and googling all day…

Update: I totally deleted my function.php and problem persist, so really its somewhere in other template files…

Update2: this is my single article img, its correct, but on main page where are excerpts there is wrong sizes as I posted here before.

<img src="http://www.danielkral.cz/wp-content/uploads/K9mailLogo-180x180.png" alt="K9mailLogo" width="180" height="180" class="alignleft size100px size-thumbnail wp-image-5330" srcset="http://www.danielkral.cz/wp-content/uploads/K9mailLogo-180x180.png 180w, http://www.danielkral.cz/wp-content/uploads/K9mailLogo.png 300w" sizes="(max-width: 180px) 100vw, 180px">

Please understand that I dont need specially sized images, it is enough to change default thumbnail size, what I even did in wp settings… but now Im facing this issue, that thumnails css and sizes are incorect when displayed on archive template, sorry for longer descrition I should do that first time yet… 😉

Hi, I found the issue, not actual function in my Own theme: heres the code which if I disable , everything works fine. Sorry for incovenience.

function XYXcustom_tax($args) {
global $wp_query;
global $post;
$dk_page = get_page_by_title( 'foto' );
$je_fot = has_parent( ($wp_query->post), $dk_page->ID) ;  

if( is_tax( 'attachment' ) || $je_fot )       {
    $args = array( 'taxonomy'  => 'attachment');
    $args['largest'] = 1.8; //largest tag
    $args['smallest'] = 1; //smallest tag
    $args['unit'] = 'em'; //tag font unit
}
if( !is_tax( 'attachment' ) && !$je_fot)     {
    $args = array( 'taxonomy'  => 'post_tag');
    $args['largest'] = 1.8; //largest tag
    $args['smallest'] = 1; //smallest tag
    $args['unit'] = 'em'; //tag font unit
}
return $args;
}
add_filter('widget_tag_cloud_args','dk_display_custom_tax');

Please if you get the idea where is the my code loosing actuality, and why this code caussing the missing envelop tag for tag cloud, please would be kind to tell me… Thanks, and happy New Year!

Thats it: was not compatible due to taxonomy reallocating, dont know why there must be:

$args['taxonomy'] = 'post_tag';

for working switching the tag cloud in the new WP…
