When creating a traced link directly on an image the url cannot be reused on other links in the same mailing – it does not appear in the list of links, global or otherwise.
See Screen dump 1.
The workaround is to take the id of the link from the url (see screen dump 2) and manually insert it as more links with the brackets and “spmLink” (see screen dump 3).
In version 7.x the link url was displayed and could be copied directly (from what is equivalent to screen dump 1).
