I have tested it again, it works with Joomla 3.10.11 and Helix Ultimate 2.0.11 but not on my new plattform (Joomla 4.4.4 and Helix Ultimate 2.1.0)

Also in the article list on mobile, the images are now zoomed and no longer displayed in their original form.

Any idea?

Hi Hans,

Helix Ultimate: Template Options > Blog > List - check what you have set in "Blog List Image" area

In tab "Image Sizes" you can also uncheck from Thumbnail.

Hi Paul,

thank you for your support.

In Blog List Image area Thumbnail is selected.

In Image Sizes Thumbnail was selected 600 x 340. After unselect and new article, same effect as before.

In article list the images are zoomed, too.

Here screenshots from the differences. And as I wrote they came after update but I don't know which update (Joomla or Helix). I did not inserted articles and pictures again after updating.

On Joomla 4.4 image is bigger (not cropped), users can see more details.

Can you check on J3 what size of image was used in that blog view

Yes, more details but not the whole picture.

J3 Thumbs: 600x340 Small: 100x100 Medium: 300x300

same as in J4

Hmm.

Can you share Admin Access to J4 version + preview of J3 (just URL).

You are wellcome

Hi Paul,

have you already had time? Any results?

Thank you.

Looking already.

Check now, it was not changes in Helix itself or Joomla - becuase in Aktuelles you used addon Article.

I used only that:

.sppb-addon-articles .sppb-addon-article-layout-content img {
    width: 100%;
    height: initial;
    object-fit: cover;
}

Hi Paul,

thank you very much for your support. With your Custom CSS it's fine now.

Did I something wrong or why is it necessary to use this CSS now?

Probably during SPPB 5.4 update... something was changed.

I used that CSS already
