My method of posting a pic:

1. Go to https://catbox.moe

2. Drop image file in the blue upload box.

3. Copy the URL that will appear right below the box when the upload finishes.

4. In your GAW post type something like "...my image..."

5. Highlight "my image" then click the link icon at the head of your post. (See the Bold Italic Quote Link icons? Here's a pic)

Or you can just type: [my image](https://catbox/url/path/here)
