There are stylevars for nearly all the folders, you pre-define the folder you're hosting the images from within the stylevar area itself example:

AdminCP > Styles & Templates > Style Manager > *Edit Stylevars of said style > Use the search filed at top of the stylevars and search for "imgdir" (without the quotes) and now you can define what the /misc/ directory is and other directories within that particular style you'll see the directories you can specify locations too when you do a search for imgdir.
