Interesting. Here's what I can detect:
IF I am logged in, then the image appears both inline and when I click the link.
This is true for Firefox (Windows), Chrome (Windows), Internet Explorer (Windows), and Safari (iPhone).
If I am not logged in, then the image is not visible (I get a red x above, or Invalid Attachment.)
There have long been complaints about how vBulletin handles images. There are numerous hacks and plug-ins one can install, however, I loathe to do so since these plug-ins have shown to be a vector for attack on this very installation of vBulletin (hence they got removed.)
Some things you can check:
- Make sure your bookmark or address includes the full www.vftt.org prefix. I do have the web server set up to redirect, but there might be cases where this does not work. If you are using just vftt.org then the cookies (saved login information) for www.vftt.org will not be passed along (and vice versa)
- Try it in another available browser
In the past, there was a problem with storing attachments, however, we now have unlimited disk space so that's less of an issue. I still do recommend, in general, that images be hosted off site and linked to using [img]...[/img] tags as described in the Site Help sticky post
and in the FAQ
I assume you (you who cannot see the image above) can see my earlier contribution? That image is hosted externally and not subject to any login requirements from vBulletin.
p.s. ETA - I cannot access the web server logs from work. Tonight, I can possibly look for errors in the logs corresponding to those of you who are having problems. If not tonight, possibly some other night... if anyone wants to volunteer, let me know, and we can talk off-line about how to test this. I'll also run a test or two when I'm logged out to see what the web server is logging.
