Thanks Stuart,

It possibly could be, the sticking point really is its use of the GregorianCalendar class which really helps to overcome issues of leap years etc. If such a class existed or could be written for PHP then it would be possible… humm, there is already the Calendar block… so perhaps just a matter of allowing the upload of images on a per month basis, just like the Grid format does with sections. Quite a bit of work! For now I’m very happy with it, and with what it demonstrates in terms of the fundamental beginnings of more complex systems like WordPress and Moodle, that follow the same dynamic ‘template’ / ‘output’ substitution pattern :).
