How can I specify where an image is uploaded I have a slideshow block that does a slideshow for a news stories that take two images.  An image for the page and a teaser image for the slideshow.  but the image never shows up in the slideshow.  The image url is sites/default/files/styles/mt_slideshow/public   but the actual location of the image after its uploaded is sites/default/files.   so is there a way to force the image to be uploded where this site is looking, or change where the site looks to where the image  is uploaded?
In your site log in as adminstrator and go to 

'/admin/config/media/file-system' 


and you can find the place where you can define your path to save any uploaded files.

for Example your siteis example.com you have to access 

"**example.com//admin/config/media/file-system**"  as Drupal Administrator and you can change the path there. 

image URLs messing up 

possibly this will give you a answer
