Simply folder which directory you wish to upload to (it goes in the root as standard, or you can create a new one). To put files / images into a folder, first select the folder (so that the name of it turns red) and then browse for the files on your hard drive.

To add a new folder within an existing one, firstly select a directory so it is red, then use the 'Create folder' link on the top right of the panel.

When you have selected the file or files you want, press the upload button and the files will be uploaded to the directory you require.

You can upload up to ten images at once like this. No resizing takes place.

Please note that image greater than 100k are really not suited to the Internet. First resize them, then upload.
