Tides .gif Update Intervals

I’m using WXTide32 with WD.

The text data is updating fine.

My .gif file here: http://217.199.187.197/otronics.co.uk/Weather/tidegraph.gif only seems to be updating once, maybe twice a day. Is this correct?

The tides option in ‘Internet File Creation & Uploads’ is set to create/upload every 30 minutes.

If I go into WXTide32 direct, it always updates immediately and shows the current ‘Time Now’.

Thanks.

But the info only changes once a day though

Thanks for clarifying.
