A bit of an unusual post, but just to say thank you. I followed our leader's instructions for using random images as a component, and it worked for me. I have not made any mistakes in the code, inserting my url's or anything.
This is all because of the support I have had at this wonderful site. I have the confidence to play with my theme layer now. Though I do still make a theme layer to play with before putting anything into my main one.
