The html of the post looks fine:
HTML Code:
<a href="http://imgbox.com/acsoujoC" target="_blank"><img src="http://t.imgbox.com/acsoujoC.jpg" alt="" onload="NcodeImageResizer.createOn(this);" border="0"></a> <br>
<a href="http://imgbox.com/admSutOP" target="_blank"><img src="http://t.imgbox.com/admSutOP.jpg" alt="" onload="NcodeImageResizer.createOn(this);" border="0"></a></div>
If I try to load the first thumb (
http://t.imgbox.com/acsoujoC.jpg) I get a redirect ( 301 Moved Permanently). The redirect target gets a 404 Not Found.
Code:
curl -Lv http://t.imgbox.com/acsoujoC.jpg

The second thumb also does a redirect, but here it succeeds:
Code:
curl -Lv http://t.imgbox.com/admSutOP.jpg -o x.jpg

I can think of two possible reasons for the different results on different forums:
- browser cache
- the forums somehow mangle the urls when rendering the html. Could you post the other forum page (I do not know if this is allowed) or the HTML snippet of the other forum (via "View selection source"). If the HTML is the same, its a browser thing. If the HTML is different, its a forum thing.
