Once you have created an Image Gallery can you add more photos to it, or do you have to make another one?

When I am done with the pics that I have taken can I delete the image gallery that I have created since it looks like you can't add new pics to the original one that was made?

If it's like other posts, you have a short amount of time to delete. After that, no. Pics not being deleted was one of Rick's intents with the Image Gallery. That way threads that benefit from the pics posted don't lose their value when they're removed from another photo hosting site.
