Number one child is now fine, number two is geting there, so I'm still on a go slow.
Yep, you were correct in your answer to me, browsers not being able to display progressive jpegs seems to definitely be a thing of the past, Cool.
Next question I have is the naming convention for images.
I have been naming my images without any spaces between the description because I am not sure if you are restricted to a certain amount of characters
Would I be better to have named it ball_yellow_large.jpg so that the web spiders have a better chance of indexing pages (I hope that makes sense).
