Yes, be considerate of users on slower Internet connections. Not everybody has broadband speed.
For anybody to give you help, they would need to see the full image anyway so you should make it available somewhere (as smaller image would make text unreadable). Normally you'd upload such an image on for example http://imgbin.org
and then include the download link in your post (that website gives you that link after uploading your image). Or you can include the download link in rimg tags (see the rimg button on the right of the markup buttons when you post a reply), which will include a clickable thumbnail of the image in your post. I've taken the liberty of doing that for your other post, so you can edit your first post there to see an example.
A more conservative approach is to use the terminal, as you can copy text from the terminal and include it in your post (not wasting storage or bandwidth). See your terminal's Edit menu. The same information as you displayed can also be gotten by running for example the command:
- Code: Select all
sudo parted -l
And you could then include the output of that in your post, inside code tags (see the markup buttons row for that), and this would give the same information as the image.
