I have ShareX like Dante suggested, Easy enough to use, I get my screen ready and snap the shot, it downloads, opens and looks great, But I am lost from there, I can click and drag, even post it to other chat formats and it posts fine, but here in Forums it comes out as a URL and No Photo. Any Suggestions?
When you make a post and want to add an attachment, look at the lower left section as you create a post, just below the text box and you can see "attachments and other options" link
Before you hit post, click on the attachment link
Then you just browse to the screenshot located on your computer and select it, then upload button and it will post with the photo and the text
