oh. well their are different ways to do that. in the past witch still works to this day is if you don't have Eclipse active it should be to the botom right two types of links, with are codes to the image you are viewing
if you copy that code example and then put that in the description on an image you are uploading it will either become a link itself or a hole thumbnail displaying the image. or you just copy the ''
bar with the hole text with it
and it will do the same.
out of late the last option is what i've use and i get the thumbnail.
to get a persons profile image displayed it requires a simple coding. like lets say i'm gonna code my own profile in to this meaning
this is how i do it.: : icon Black-Wing24 :
you see there is a separation between the words if i attach them without separation anywhere this is the results
and if you click the preview button you can see if the coding works or not
so always dubble test befor you post, and you should be good to go
