[Solved] Remove image title

@magdalena,

Use this CSS code:

#wpf-content-blueimp-gallery h3.title {
    display: none !important;
}

The CSS code should be added in the "Custom CSS code" textarea, located in the Dashboard > Forums > Settings > Style Tab. 

Please don't forget to delete all caches and press Ctrl+F5 (twice) on the frontend before checking to reload the updated CSS file.
