Been there, done that...
...admittedly, not
quite as extreme, but I believe track like that is known on this Forum as "Jordan Track"
Although as Photobucket decided last night to suspend image hosting unless you pay an enormous fee per year, for now I can't post a pic of my trackwork.

Flickr does all the resizing work for you and also gives a link so that readers can go and look at the full size image, or others you might have not linked to.
It does run the risk of falling over like any other image hosting site, but I've been with Flickr for nine years. I'm one of the ones still paying for a pro account which are no longer available which I think have one or two other stats and tracking functions. Even then it's not expensive, £25 or something a year and Flickr has seen a lot of other similar photo sites come and go.
I personally upload from my PC and resize to suit, but if you want a quick, free and easy option from an online source then Flickr fits the bill. Especially if you're linking photos across several sites, some of which may not have the image hosting facilities that WT has.
You can have your thread back now Ken lol.
