Geniuses click here :) Help with image attachment page

Hello,

My url is http://www.sapnamagazine.com and I am using the Gazette Edition. We just posted a public gallery where prospective models can upload photos:

http://www.sapnamagazine.com/models

If you click a thumbnail, you are taken to the attachment page.

Customization number 1:
I’d like the image on the attachment page to be larger.

– If the image width is larger than my main column, I’d like the width of the image to be scaled down to the width of my column.

– If the image width is smaller than my column, I’d like the full size image to be displayed.

Customization number 2:
For some reason, the styling of the attachment page titles are different. Some are like this: http://sapnamagazine.com/models/faiza-husain-4/. And some are like this: http://sapnamagazine.com/2010/sapna-model-search-2010/sarika-bhardwaj-5-2/. I’d like all titles to have the same styling (preferably the latter example, which is the same styling as the titles for my single posts).

Please, your help is greatly appreciated!

Thanks in advance, geniuses 😀
