Hello Sol !!
welcome to MJJCommunity !!
I saw your query in the 'Ask Us' section and wanted to give a little more instruction. In case you might need it... I have switched on your complete editor, so that you will see all the options available when posting a message on the forum.
To include an image that is not uploaded as an attachment and is located on another website, you can do so by copying the full URL to the image, (not the page on which the image is located), and either pressing the 'Insert Image' icon or by typing after it, ensuring that you do not have any spaces before or after the URL of the image. You can insert pictures from your albums in this way too.
If you need anything, please feel free to call on any of the staff, for helpful and courteous assistance :)
