I’m trying to load a watermark image into a plugin to use on all my pics but WP says there’s a problem loading. The plugin is called Image Watermark 1.5.6
The watermark is a transparent PNG and the advice from this person has already been actioned as per this support page https://wordpress.org/support/topic/transparent-pngs-1
The watermark appears on mobile device but with a black bar as background to the watermark. It does not appear on pictures on the desktop version of the blog.
The blog is lanebylaine.com
Please help resolve. Thank you.
