The sizes don't bother me sitting at home on a 100mbs broadband connection, but it would if I were at sea accessing via a slow connection on my phone. Dimensions of 1,024px × 768px seem unnecessarily large and sub-optimal. Reducing it to 400x300 and a reduction in quality reduces the filesize and still conveys the message, although it won't win a prize in a competition!I did optimise them. sorry if you found the images too big. I am not an expert at such things, but if you look at the bottom right of the pics you will see the software I used embossed. If you have any constructive technical advice to help me make them smaller I am open to it as using that bit of kit is about as advanced as I get at such things
I did it at http://www.imageoptimizer.net/Pages/Home.aspx
Or, simply upload the "original" image to the forum rather than Flickr and let the software display it as a thumbnail. That way fellow forumites only download the entire ~2.5MB of files if they wish to do so. The thumbnail is less that 8kb in size!

I think we get 10MB of storage each, so you could upload ~50 images in the size/quality you posted.
