background of a png image is displaying black

Hey trustedone,
Thanks for your question, please link to an example page so we can investigate, could the black be your background color?
If you are using any image optimization plugins try disabling them.

Hi,

Thanks for that. I’m not sure I fully understand the problem you are having, do mean the border around the image just before the footer? If not, then please post a screenshot highlighting what you are seeing on your end.

Hi,
Thanks for the login, I reviewed your preloader image, and while it has the PNG extension if you paste the url into a new tab and try to save it, it saves as a WEBP image:

so I believe that the image was converted by one of your plugins when you uploaded it and broke the transparency
Try uploading your preloader image again in the PNG format with a different name and see if works while all of your plugins are disabled.
If not please link to your transparent preloader below, but not the one in your media library as it is no longer transparent.

Best regards,
Mike

Hi,
This image is a proper PNG ▸ t-and-r-logo-white-1.png
your preloader is not ▸ trustedblue.png
If you don’t have a backup of it then try recreating it.
If you do and it still doesn’t work then upload a copy to DropBox or such so I can check that it is properly working.

Best regards,
Mike

Hi,
When I test the images on my demo install they are transparent, see my text page below.
Try removing your plugin and see if that corrects.
If not try creating a test install on a new WP install with no plugins and see if it works like on my install, don’t make a clone of your site because you don’t want to carry the error over.

Best regards,
Mike
