Thanks for comments about Ilka, yes she is as fit (and healthy) as anything and I would not say we have been giving her to much exercise either, though she gets quite a bit of free running in the field and playing with Sid, so has built up muscle by her self really, it's becoming more and more difficult to get a good photo of her stood still!!
How I get the pics to be 'clickable' to go bigger, is first I only put them on the post I am making one at a time, then after I have published it if one or two won't go bigger just edit the post, delete the problem one or two, then re-add them and they should become 'clickable' though you might have to do what I said a couple of times, and now I still load one at a time but they all seem to work. I have no idea why it works but it does for me.
My camera is this one http://www.panasonic.co.uk/html/en_GB/479303/index.html I wanted something quite good but small at the same time, will try it out again tommorow, now I sort of know how it works, see if I can get any better.
