photo gallery application

Hi, I am a photographer who needs an easy way to post photos for my customers to review. It should have the basic features - thumbnails, multiple albums, and password protection. Ideally, it should allow me to select a very large image to upload and automatically reduce its size so that I don't have to reduce the image size before uploading. I generally prefer applications built on open source software so that I can find someone else to make changes to it in the future if I cannot find the original developer. Some of the open source software I have heard of are 4Images, Coppermine and Gallery. I am not familiar with any of these so am not sure whether they are a good fit. Please tell me what you propose to use. In your response, please point me to a photo gallery that is similar to the one that you are proposing to create. Thank you for your interest, [UPDATE: DO NOT SEND ME FORM EMAILS TELLING ME HOW WONDERFUL YOU ARE OR ASKING ME TO CONTACT YOU IF I AM INTERESTED. I WOULDN'T HAVE POSTED THIS PROJECT IF I WASN'T INTERESTED. RESPONSES WITHOUT PRICES WILL BE DELETED. IF YOUR PRICE IS GOOD, I WILL CHECK OUT YOUR PROFILE. IF YOU HAVE SPECIFIC QUESTIONS, PLEASE ASK, BUT DO NOT SEND ME A GENERAL MESSAGE TELLING ME YOU WANT TO DISCUSS IT.] -- Steve
