i'll have to push everything on a server first - currently only working on xampp

Hi & thanks for your answer,

I think it partly did the job, yet, now I have 2 different issues resulting from this (see images):

1. The justified gallery adds the alt-description as caption (this shouldn't be the case though - I haven't added a caption) -> image1

2. The grid gallery adds medium images instead of the correct ones -> image2+image3

I did a little tinkering now myself and changed a few lines (below, marked with /*TODO2*/).:

--------------------------------------------------------------

if( $posts ) {
foreach ( $posts as $imagePost ) {
$caption = '';
if( $imagePost->post_excerpt ):
$caption = $imagePost->post_excerpt;
endif;
if( $imagePost->_wp_attachment_image_alt ):
    $alt = $imagePost->_wp_attachment_image_alt;
endif; /*TODO2*/
$get_full = wp_get_attachment_image_src( $imagePost->ID, 'full' );
$get_masonry = wp_get_attachment_image_src( $imagePost->ID, 'penci-masonry-thumb' );

if( $type == 'single-slider' ):
$output .= '<figure>';
$get_masonry = wp_get_attachment_image_src( $imagePost->ID, 'penci-full-thumb' );
endif;

if( $type == 'masonry grid' ):
$get_masonry = wp_get_attachment_image_src( $imagePost->ID, 'penci-thumb' );
endif;

/*$output .= '<a class="item-gallery-'. $type .'" href="'. $get_full[0] .'" title="'. $caption .'" data-rel="penci-gallery-image-content">';*/ /*TODO*/
$output .= '<a class="item-gallery-'. $type .'" href="'. $get_full[0] .'" title="'. $caption .'">';

if( $type == 'masonry' || $type == 'masonry grid' ):
$output .= '<div class="inner-item-masonry-gallery">';
endif;

if( $type == 'single-slider' ){
$output .= '<img class="owl-lazy" data-src="'. $get_masonry[0] .'" alt="'. $alt .'">'; /*TODO2*/
/*$output .= '<img class="owl-lazy" data-src="'. $get_masonry[0] .'" alt="">';*/
} else {
$output .= '<img src="'. $get_masonry[0] .'" alt="'. $alt .'">'; /*TODO2*/
/*$output .= '<img src="'. $get_masonry[0] .'" alt="">';*/
/*$output .= wp_get_attachment_image( $imagePost->ID, 'penci-masonry-thumb' );*/
}

if( $type == 'masonry' || $type == 'masonry grid' ):
$output .= '</div>';
endif;

$output .= '</a>';

if( $type == 'single-slider' ):
if( $caption ):
$output .= '<p class="penci-single-gallery-captions">'. $caption .'</p>';
endif;
$output .= '</figure>';
endif;

}
}

This fixes issue 2 (medium images instead of the correct ones -> see image 4), 

yet I still strangely have the alt-description as caption...(issue 1 still exists...)

Any ideas?

thanks, i will take a look

No, I mean a missing alt-description. I just deactivated all plugins non-related to this theme to make sure that there is no interference.

1. I added an alt-description on all images. (already did before) (see image)

2. added a gallery

3. checking the image of a gallery out: no set alt-attribute (see image)

Hi and thanks for your answer.

A missing alt-description doesnt seem to be the issue though, as I have added alt descriptions to all images beforehand in the media library. (See both images: alt desc. on image added w/o gallery gets shown (2.jpg), image in gallery doesnt... yet, there is an alt-attribute (but empty) in the img-tag (1.jpg)). The "= 'alt desc'" after the alt-attribute is missing on all gallery images.

Hi guys! Thnks again for your help with another ticket :)

I'm still working on a relaunch of my site and using this theme on a copy of the site via XAMPP to get the redesign done and just switch everything afterwards…

Yet, I got 1 issue though:

I noticed that the alt descriptions of the images seem to be missing when I have added a gallery into a post (see image)

I’d appreciate any help :)
