You also reversed the "<span style="color: #6600CC">]</span>" at the beginning of the link, too:
[img<span style="color: #6600CC">[</span>
https://www.yenko.net/ubbthreads/pics...1640-image.jpg[img]
It's always <span style="color: #FF0000"><span style="font-weight: bold">[img] "photo location" [/img]</span></span>
Finally, when everything is right and it <span style="font-weight: bold">still doesn't post-it's usually due to <span style="color: #FF0000">special characters</span> in the "file name"...like <span style="color: #FF0000">*</span> or <span style="color: #FF0000">_</span> or <span style="color: #FF0000">-</span> or <span style="color: #FF0000">&</span>. </span>
To solve this issue, before loading onto the site, rename it as "<span style="font-weight: bold"><span style="color: #6600CC">1.jpg</span></span>" (without the quotes) [img]<<GRAEMLIN_URL>>/beers.gif[/img]
