Not working with a particular image on a page

The URL of the first image is not correct – it contains a trailing space:

<a href="https://yoursite.example/someimage.jpg ">

Besides the fact, that an URL should not end with a space, the plugin will then also not recognize this as a valid image since it does not end with “.jpg” but “.jpg ” (note the space at the end). Browsers may be a bit more tolerant with this and still open the image, even if a space at the end is present. However this should be fixed.

Either correct the HTML code manually or if this is created by some gallery plugin ask the maintainer of the gallery plugin to fix this. URLs must not contain a space at the end.
