well, i've got good news and bad news... or rather, just a bit of an unpalatable answer to your question about deleting your gallery...

go to your gallery, and as you are looking at your images, you'll notice a nice little red trashcan icon next to EACH image.

[sarc]now here comes the exciting part...[/sarc] you need to delete each image one by one using the icons. no, there is not a 'nuke my gallery' button the way there used to be with the old site design; you are now required to remove images individually.

here's a tip though that i discovered:

you can always turn it into a game!! [rolls eyes] -

even though it is image by image, if you are quick with a mouse, you can actually click 3-5 trashcan icons before the page rolls over and the site WILL recognise all of those clicks, thus eliminating the gallery can potentially go a touch faster than one might assume at first....

fun times, fun times
