I have finally been able to solve the problem! It took a while to see what the problem was because in the html view pictures loaded even though they were properly uploaded and named.
Finally the line has been as follows:
PHP Code:
<center>
<vb:if condition="$post['field10']">
<img src="{vb:stylevar imgdir_misc}/equipos/{vb:raw post.field10}" align="center" alt="{vb:raw post.field10}" border="" /></vb:if>
</center>
Maybe it is not spelled correctly but it works, recently I'm starting with this and I'm doing my best, and I'm starting a forum from the start.
I am very grateful that I have helped!
