Having just gone through the process uploading is easy, it's what you want to do with the image after that is the issue.
Having said that when uploading you still need to make some provision in the instance of where people try to upload an image with the same name. i.e., if you have two people whose name is David and that's what they name their image - David.jpg, one image will overwrite the other. Also it's not good for there to be spaces in the file name, so David Alan Smith.jpg is not desirable but David_Alan_Smith.jpg is. It takes some technical know how but you can strip out the white spaces and replace them with underscores, plus to overcome the duplicate image problem if it arises you can add a randon number to the end of the image name  David_Alan_Smith_3578976.jpg
Then of course what are you going to do with the images? Are they intended to be shown on a webpage or are they just for you to personally download and look at/work with. If they are destined to be shown on a webpage then how are you going to get them onto the webpage, manually or automatically. If automatically then you will need to set up a database to store the name of the image which can be retrieved and displayed on a webpage.
Plenty to think about.
