Thank you Neyjour. That was most educational (and some very nice fallen trees as well).

I can now see that its not just a case of throwing it up there on Panjo's page, but preparing the zip folder first. I notice how you have put your rights and permissions for the graphics in the read me file. I may just copy that file and list the stair shadows in place of your tree list... if you don't mind that is?

I have about 15 different sets of stairs (different numbers of steps 1 - 15, and the banister shadow. All these could go as one zip to the customer.

I'm understanding a lot more now. Thanks for your help
