In IE I do get the option to open in new tab or new window, but neither produces a full image.

TBH I'm not sure what that implies but, as I said, I can't run IE here so I know zilch about it. But it's got to be a clue to something, and I was hoping it might provide that "Aha!" moment to someone more knowledgeable than I am

@ all- Any takers?

Here's what I see with all the above browsers and various IE settings:

Clearing my cache made no difference.

I have had similar problems in the past although I cannot recall the exact circumstances. I think that the problem concerns the maximum number of TCP connections (in this case image downloads) that can be handled at any one time, both by Internet Explorer and also the server being accessed. While IE and the server in question may handle maximum allowed TCP connections correctly, some firewall/antivirus software can foul things up by opening new TCP connections without closing existing connections. This can overload servers that are incorrectly configured to accept a large number of TCP connections and may cause downloads (of images) to time out.

Without messing around with software settings, the easiest solution may be to change your browser or firewall/antivirus software. Kaspersky seems to have caused such problems in the past and may still do so. Unfortunately, I do not have the time to research this. You should search for "kaspersky maximum tcp connections" and "internet explorer maximum tcp connections" if you want to have a go yourself.

Login to your router and set the MTU to 1500 please

I'm with Zen and using a Billion 7800n (wired).
I have noticed in the Billion log that when it has lost connection in the past, it does attempt twice to change the MTU to 1500.

From what I can tell, the router firewall is disabled. I think the router MTU is 1492, but has been for over a year now.

Ditto, but it was back in Netscape days when that was a user-settable parameter.

I had that in mind when I suggested the right click, open in new tab option- the fact that it didn't work correctly either suggests that the number of connections may not be the reason.

Unfortunately it doesn't suggest what the reason actually is

She may not be able to- I used a 7800N for a while and it wouldn't let me set the MTU above 1492.

It was a PPPoE connection (FTTC) so it was correct for a computer MTU of 1500, I don't know what Trisha is using. It might be easier to drop the MTU on the PC.

I had a little time this afternoon, and because I always use a lot of image based art related sites, I looked at lots of art content and gallery sites - only one gallery site had some images that didn't load as on the other two sites.

Whatever it is, it's something that is only on a smaller number of sites.

Have you tried changing your DNS servers?

Thanks for the input Mick, Moto & Bill.

I sent Mick's thoughts to my UK Kaspersky tech to see if she can throw any light on the problem. Had no reply yet, and it's usually quick, so may be holidays.

I eventually found the MTU in the Billion (recalled seeing it a year ago) - it is at 1492. As I said before, if it disconnects, the log shows that it tries twice to change the MTU to 1500 and then gives up and completes the connection.

I've currently got a not perfect connection, but definitely the best it's been since June: 1092 / 9349 kbps (ADSL2+). I saw they put interleaving on in summer and re-set the noise margin early November. Whatever, it's not always responding fast but is stable (up 51 days - even when the down SNR dropped to only 0.8) - so if trying to re-set MTU would mean disconnecting, I'd hesitate to mess with it.

It's obviously not a common problem as only camieabz can see the same thing so far.
Shall I see if Kaspersky do know of any reason I'd be getting this image loading problem? - it's not hugely important for now as long as it doesn't get worse in the meanwhile.

There's no harm in disconnecting a few times. No need to go for record Uptimes!

EDIT: Always worth trying a simple quick experiment to see if it cures.
