Yes, putting images in the gallery is fine, and they will be visible to all registered, logged-on users.
You can make them appear inline by using the same kind of code as you would for images stored anywhere else on the web, so your Jupiter image (of which I am slightly jealous, by the way) can be linked inline with the code
Code: Select all
which produces the inline image
The reason I'm not recommending the gallery as the primary repository for images is that we have a fairly small quota for images hosted on myfastforum, and as our membership grows, it is likely to be used up by avatars.
If you don't have a website, you could set up a free account on a dedicated image hosting site like <a href="http://www.flickr.com">Flickr</a>, which is what I did for the eclipse image above.
Whether you use the gallery, or an image hosting site, the images will still be visible when your PC is offline.
