Nice signature image; exciting times counting down now I guess.
You did a good guide to sharing photos for those that have problems with that. But I wonder
if you have seen this in the FAQ
Is there a limit to the size of an image I can have in my signature?
We ask that you keep your images relatively small. As a rule, please do not exceed 600 x 125 pixels and/or 35k for a signature image. This will ensure that the forums load quickly for all users.
At 640 x 175, 155 kB, your signature image is a bit over that in dimension and quite bit in kilobytes. But things change over time, so I don't know whether the FAQ is up to date or not. And signature images also tend to change over time... I have a nice 100 Mbps connection so I'm not complaining about "speed",
but other people in this very much global forum might have other connections; and the size might be a bit of a distraction in a long thread.
