Interesting - and there did not seem to be any problems with your illustrations when I clicked on your link.
How do you do your blog - direct on the Blogger site, and then uploading the pics on the same wave length (if you see what I mean). Or do you upload the pics, after clicking on HTML and then uploading them.
On www.ColdhamCuddliescalling.blogspot.com I have found that sometimes I lose my photographs if I don't change to HTML. Frankly, I don't understand what HTML is, but I've worked out a method of uploading my pics much better that way.
I also sometmes draft my blog off line, copy and paste it to the Blogger site and then slot in the pics at the appropriate place(s) via HTML.
All takes time, but one gets there in the end. It also depends on the length of my post: the longer ones are better done off line for me, because my elderly computer tends to choke if I'm on Blogger for too long!
Good luck - and keep us posted as to how you get along. Isobel
