Hi, I have the image upload function in my form but would like to be able to have clients upload a folder of images also. Can this be done and if so how?
Unfortunately this isn't possible ( sort of ) with plain HTML. You could instruct your users in how to zip / create an archive of their folder and then upload that zip file.
Multiple file upload ( like is done in GMail ) is only possible using 3rd party add-ons such as flash: http://stackoverflow.com/questions/135123/how-can-i-get-gmail-like-file-uploads-for-my-web-app
