Thank you!

The post "Australia - part 2" is the only post done directly on WordPress. *All other* posts were imported from Blogger.

I never reduced the size of my photos when uploading them to Blogger so although they look small on the blog page they are quite large files. And they came over to WordPress that way - large(ish) files that look small on the page.

I started with Australia - part 1, then Bali part 4, Bali part 3, etc slowly working my way back through the posts resizing the photo files (making them smaller), but having them look bigger on the blog page. Of the posts where I have done the resizing all horizontal photos are 1280 pixels width, all vertical are 875 or 900 height. All are resolution 72.

In the post "Australia part 1" when you click on any photo to enlarge it it simply enlarges and fills the monitor space, then you can go back to the post after looking at the enlarged photo.

This is also true in the post "Bali part 4" UP UNTIL the first photo of egrets. When you click on the photo of Goa Gajah it opens as described above.

The next photo is one of egrets and when you click on it to enlarge it it opens into a page that has the blog and post titles, the search and comment features, and worst of all none of the vertical photos fit on the screen. *All photos* that I resized after this one do the same thing. So suddenly, in the middle of a post, when I've done nothing differently from the first half of the post, or the previous post (Australia part 1) the format changes. For no apparent reason.

I'm completely puzzled by this, and don't like it at all. I hope someone can help me change this so that they open like the photos in "Australia part 1" and the first half of "Bali part 4".

I can see that the coding has changed but I don't know why.

In case this can help here's the coding of a photo that enlarges the way I want it (simply filling the screen with no wording around it)
<img class="aligncenter size-large wp-image-1982" title="" src="http://alisonanddon.files.wordpress.com/2012/04/blog-dscn9427.jpg?w=1024" alt="" width="1024" height="768" />

And here's the coding of a photo that has all the writing around it (blog and post titles etc)
<img class="aligncenter size-large wp-image-2036" title="" src="http://alisonanddon.files.wordpress.com/2012/04/blog-dscn9587.jpg?w=1024" alt="" width="1024" height="699" />

I hope this is clear, and that someone can help. I'm not very good at the technical language.

Thanks.
