format for designing a website for a beginner?

I'm designing a photography portfolio for someone that has little to no computer experience. They want to be able to change the pictures on the pages and in the gallery once I'm done designing the page. What format (html, php, etc.) should I use that would allow them to merely upload a picture and it does the rest?

Set them up with a Coppermine gallery. Very user friendly and customizable.

I like Gallery[=http//gallery.menalto.com]Gallery much better than Coppermine, personally. Very easy to setup and get going.

I was planning on doing that for their gallery page. however they want the ability to change the pictures on the main page. for instance if they wanted to replace the large image like on this site

http//www.cmp.ucr.edu/

they wouldn't know how to resize it to fit the html. Is there a quick way of doing that or possibly a program that does that easily?

HTML will resize for you if you specify width and height attributes to the img tag. However it still downloads the fullsize image, it's just resized on the browser side. If you want to actually resize the source image, there are lots of programs to do that.

But if they can't figure out how to change the src attribute of an img tag, they've probably got no business running a web page. ;)

i would just make the whole thing in php and load from a database. then make them an admin page where they browse to the file they want to put up, in the proper section, and have it replace what already exists there. this is strictly from a coding point of view, there might be picture-specific things like the ones others mentioned that would be better suited, but i only know coding
