What I'm trying to achieve: Have images in blog posts take the full width of a blog post, and keep image proportional. Aka, a portrait image will end up being bigger than landscape.
The challenge, I'm not using images from my wordpress server, but from smugmug. Hense, I'm using embed images like this one (just drop the link in a post written in html, not wysiwyg) http://nickpelletier.smugmug.com/Category/From-nickpelletiercom/21943413_P6Mzn6#!i=1750174498&k=5SsSHBq&lb=1&s=A
I tried through settings here: Settings -> Media -> Embeds and leaving a blank value for width. This worked for landscape images, but not for portrait images. Portrait images were still using the height making the resulting width different for any picture with a different size ratio.
I tried many template (including ten eleven) and all have the same problem. Hence, I think this is how Wordpress is actually made to work.
This being said, I'm looking for how I can change this behavior in the code (template if possible, wordpress if worst case).
I'm a programmer by day doing backend code. I'll probably be ok with the code part, but I have no clue of php, wordpress (this is my first blog I'm setting up) and am fairly new to web\html. Any clue of where to look first would be appreciated.
--Edit Here is a page with a portrait image (first from smugmug, second from flickr) http://nickpelletier.com/2012/03/19/alphonse-et-dorimene-desjardins/
The current value in setting -> Media -> Embeds are width:nothing and height:1500
I would have liked the image to go to max width of column instead of having a height of 1500
