Just finished writing a php script for the Facebook sharing part of my app.

Allows the user to share the sudoku they are playing including an image without actually uploading the image

The board is generated from the boardstring parameter passed in to it

Woop woop!

Why use a dynamic image? Surely setting up the grid with divs would be easier? There is nothing about the board that requires it to be an image, other than maybe the font choice...

I'm going to use it as the thumbnail when posting a link onto Facebook.

For that it needs to be an image.

Can't be that hard, it's relatively simple to do in asp.net after all

In the end it was only around 10 lines of code.

Create image from background image.
For each number in the string.
If not 0 then work out coords of where it goes and place it on the image.
output image.
