Hi James, Thanks for the clarification & calcs re bandwidth & download speed.
If the problem was just the bandwidth/download time however, surely it would affect both Firefox and Safari. The 1.3 MB gif I was looking at: <http://www.paperartzi.org.au/Resources/worksshow09.gif> actually has 29 cycling images - so each image would correspond to <50kb. Firefox starts cycling in less than 10 secs - so presumably it can start cycling the images before the gif is fully downloaded. Safari, on the other hand, starts cycling after around 55 to 60 secs - more than 5 times the download time of the whole 1.3MB gif. Interestingly though, Alastair says: > the gifs play straight away for me > safari 4.0.3 > G4 1.25 > 10.4.11 So he has the same Safari version as me but doesn't see the problem on a G4 machine running Tiger - whereas I do see it on an intel Core2 Duo machine running Leopard. Ronni's explanation makes sense to me: > CoreGraphics bug,which is fixed in Snow Leopard OS X 10.6 from what I > can find out. Based on Alastair's feedback, I am assuming that this bug was introduced with Leopard? Cheers Neil -- Neil R.
