There are several ways to add photos to a Worldisround article.
When you click on the 'Add Photos' link when you are editing an article,
you are presented with these options:
Simple Upload is a barebones interface for uploading photos.
Select up to six files individually and then upload. This is the
'lowest common denominator' interface that is supported on all Web
browsers and will be familiar to new users.
Image Uploader allows you to upload larger batches of photos. Navigate your
local files and select sets of photos to upload. You can rotate
them and add titles and descriptions before uploading them to Worldisround.
Drag & Drop is a simpler version of
'Image Uploader' which is just a
download list which you can drag image files to from your operating system folders.
(Use your operating system to find your images, instead of Image Uploader.)
Copy Photo from Another Article should be self-explanatory :)
Upload from Web allows you to 'upload' images from Web URLs, e.g. to
grab photos that you have hosted on another website.
