Best way to make milliondollarhomepage dynamic image grid?

I've been thinking about setting up a image grid similar to milliondollarhomepage for a small domestic hobby idea , it would be dynamic. The grid would be around 500x500, I am wondering the best way to code this up, It can't be slow.

I am thinking it will work like this:

1. Users choose their place on the grid and upload their image.
2. The image is stored in the DB in a image type column
3. On rendering the page to the public, .NET cycles through all the uploaded images from the DB and dynamically creates the image based on each DB rows data & stored place in the square

The thin开发者_运维技巧g is I am not sure if this is a silly way to do it?

What do you guys think?

Thanks!

You're better off just recreating the image whenever somebody uploads a change. Assuming there will be far more visitors than contributors it would be wasteful to recreate the image for every request.

Your approach sounds pretty reasonable to me.

Like Gordy said; you probably don't want to regenerate the image on each visit - but your code to generate the image and save it to the file system would be largely the same anyway. Then, you can use a large HTML Map to define the individual ad's 'area'. That will let you have different mouse-over text and URL when clicked.

Again, I'd be tempted to just generate the HTML file whenever you have a new client come on. I mean, update your database and use .NET code to generate the HTML. But the static html page with a static image is going to be a lot more performant than building anything dynamically.
