Guys I am going to put my wife on now she works in tech and thus has a better knowledge of it then me.
Hi all,
Thanks for all your suggestions - I'm stumped myself.
So this is a system I built: Intel Celeron 2.93 GHz processor, 1 GB RAM, NVIDIA Quadro NVS video card (I believe it has 64MB memory), 200 GB HD. Our connection is DSL (last time I did a test at Speakeasy our download speed was 779 kbps).
We're running Firefox 1.5.0.9, and I have only one extension installed, for del.icio.us. IE is 6.0 as I've been reluctant to move to 7. Anyway, I used IE just to test whether the same thing occurs (it does). That's what really stumps me - if it were related to just one browser then I could do something but it happens on both. Also, my laptop is a slower system with much less memory, also using the same broadband connection (but wirelessly, no less), and it doesn't have this image issue.
The things I've tried include (though not necessarily in this order):
clearing cache
increasing/decreasing cache size
allowing images from MR
loading images from originating site only (oddly enough, this fixes the problem but then other websites don't work too great!) (I noticed too that the images that DON'T show up are those that are residing on MR. Images on the forum but which are hosted by photobucket or other websites show up fine.)
disabling firewall and anti-virus
running spyware scans
reinstalling Firefox, including from a fresh profile
trying linear/hybrid/threaded mode in MR forum display modes
replacing the video card
can't remember what else!
So, in summary, attached images hosted by MR usually don't show up in Firefox OR IE. It's a random thing, though, because sometimes 1 image out of 7 (in a single posting) will show up, and sometimes refreshing the page brings up the other images but most often it doesn't.
I feel bad that I can't do anything about but I'm out of ideas. Thanks for your help!
