How can I upload an image from my PC to a forum?

Nice :-)

@TomKerbal Finally! it worked. Thanks for the help.

@deepfriedfrenchtoast I'm sorry friend.
You should be able to see your picture yourself. Do you see it ?
You can also write: 

@TomKerbal any better now?

@deepfriedfrenchtoast Try Firefox perhaps.

@TomKerbal yeah, I cant place images in the description section when I upload a craft.

@deepfriedfrenchtoast And when uploading a craft, same problem ?

@TomKerbal hmm..

@deepfriedfrenchtoast Nope.

@TomKerbal I tried doing that. I made an account, uploaded an image to it and copied the Image link and pasted it into the ![ Hello World ] frame you provided.

does test 2 work?

Perhaps upload it to imgbb (free account). This was my solution for pictures to share.

@deepfriedfrenchtoast No image to see here.

@TomKerbal I tried doing it in this post. Is the image working? It just looks like a small file thingy for me.

Try something like this :

! [ Hello World ]( h ttps://i.ibb.co/.../HelloWorld.png )
