Soo to anybody that need help to post images i think this is the best way:
1) go to this web site: https://postimage.io/
2) choose your image without changing the size just like the option. Upload and wait.
3) after the upload choose the "direct link" option
4) use the code after posting the link on the forum like this:
*don't use (*) on the code. It's to show you without posting the image.
Post your images here if you like.
