Any problems with this permalink structure?

Hi everyone

So I have recently updated my permalink structures so they are as such.
http://deepbluetrees.com/%category%/%post-name%

I am looking for input as to whether or not the structure I am using is recommended, and if not, what I should change.

Categories can be reached by: http://deepbluetrees.com/%category%
Tags can be reached by: http://deepbluetrees.com/%tag%

The first problem I ran into was having the directory for images set as http://deepbluetrees.com/images

When the image name was the same as the post title, it would take you directly to the image, despite the post title not ending in .png or whatnot. I have fixed this by changing my image directory to http://deepbluetrees.com/content/images.

SO – my question is, does this present any potential conflicts? I’d rather not have to change my permalink structure again down the line, or run into any unfortunate problems. Thank you.
