PNG image not showing anymore

My signature image used to show, and now it doesn't. I haven't moved the image from where it is hosted, nor have I edited the signature text. I tested and drafted a post in the forum to show an image using the

tags, but it wont show. Is anyone else having issues? has anything changed that would prevent a png file from showing? It appears gifs work fine.

In this post (below) I have the image from my signature embedded using the img tag, but it isn't showing...

The images in this post : https://www.scirra.com/forum/what-you-may-have-missed-in-march-2018_t202385 are pngs and do display.

I can notice the URL to your image uses a "_promo" folder.

Possibly this folder has different access permissions (to be checked in your server/host provider's configuration).

Or perhaps simply the URL shouldn't hold an underscore "_".

To make sure, try providing an image from the root of your web hosting space and see if it displays more correctly.

Indeed you have changed nothing, but perhaps your web hosting provider did.

Kyatric thanks for the reply. turns out it is the AdBlock plugin in Chrome that is preventing certain PNGs and some other imgs from showing on this site. How odd. I tried hosting the image form my website and Dropbox and both were blocked.
