Why can't I post photos on the fourms

This has been going on for a month. I have new creature concepts and memes that I try post but it won’t let me. What do I do?

Does it say anything when you try to upload?

It says nothing. The button that lead to the photos doesn’t work.

If the button doesn’t work, use the snipping tool, snip and [CONT]+‘V’ into this text window.

I’m not using a PC for the fourms. I’m on a Samsung.
