First off, I give you a hearty welcome!
If you are having problems posting images or using LJ cuts, check out our User Info page. We have links to the Livejournal FAQ regarding cuts, as well as links to photo-hosting sites if you need webspace.
Please remember that all gigantor photos need to be behind a cut, as well as any posts that contain several photos - we ask that all but the first image is put behind a cut.
If you have scrolled through the links and still have questions about how to post an image, feel free to leave a comment here. I'm sure we can walk you through it.
