I’ve browsed through all of your support forums regarding getting working output out of the Image Watermark plugin. I’ve tried on 2 different web hosts (different servers), and a fresh wordpress with 0 plugins except for the Image Watermark.
No matter how many attempts I try, the images in the media library disappear and no watermarks are ever created.
I’ve tried transparent and non-transparent images. I have even tried downgrading from PHP 7.2.0 to PHP 5.6 to no avail.
It seems that I am not alone with this problem, but people are not getting responses in the forum. I am using WP 4.9.1, and the plugin says it’s compatible. Please help if you can. Thank you.
For some reason is all just started working today (apparently after an auto-update to WP 4.9.2). I received an email that said there would be a fix in the next release, however the plugin hasnt been changed. For now, all looks good.
