Hi Teej About the photo it s an old NPS photo if you have a better one feel free to replace it There are two methods for uploading photos depending on whether you want to make the photo available to just the English Wikipedia or all languages In either event get a hi res photo ready on your computer with a sensible filename that filename will get copied up to the Wikipedia If you want just English click on upload file to the left then follow the instructions When you re done there will be a Wikipedia page with the same name as your image So if you called it Katahdin jpg the correct link would be Image Katahdin jpg In the infobox replace the existing jpg link with your new file perhaps giving it a new caption If you want all of the pedias the recommended option go to click on upload file and follow the directions Getting yourself a user name on Commons may be a good idea first The extra steps needed for a Commons image is that you should find a category or article at Commons to fit the picture into I ve put the existing pic into the Commons category Mountains of the United States The cool thing about Commons photos is that you don t have to do anything special to use it again if you ve uploaded a photo named Katahdin jpg to Commons just link to it like Image Katahdin jpg here at the English wikipedia In either event you ll have to decide how you want to license your personal photo It s up to you although non free licenses are not permitted at Commons People typically license using GFDL so you can add the template GFDL on your image description page Or you can release it to the public domain with PD Hope this helps And re name check out The official US government name for the mountain is Mount Katahdin this USGS database is contains the official names of all sorts of US locations
