to post pictures, are you subscribed to facebook? f so, upload the photo to facebook, its the easiest photo hosting site. or, if you'd like, register at photobucket.
then, add the image url here in img tags. you get the tags by clicking the second icon from the left, its directly underneath the italic sign...
so you highlight your link, and click the image tag button... voila...
as for the grille cloth... im not sure myself...
the tolex... i have wondered about that... as its just vinyl not so??
you can buy good quality vinyl from material shops!!!
otherwise, if you'd like to import, www.stewmac.com is a good option...

and there will definitely be other guys coming in giving their help too!!
