You'd have to upload every file you need, unless it's uploaded to Flickr, in which case you can import them. If you need to upload many files, use Special:MultipleUpload where you can do 10 at a time. You'd then have to make a gallery through the visual editor (or use the Source editor if you're comfortable with it). I'm not sure exactly what you mean with RSS and XML. RSS is used for feeds, which is essentially a list that is easily read by computers. XML is a scripting language that is similar to HTML (which is what you would see if you pressed View Source on this page) but is used more by robots because it is more structured.
