Many apologies for being late today. Also many people are having trouble adding their thumbnail. I emailed Brent at LinkyTools and he says that he is having a problem but is working on it:
"Here's the issue... the site has over 18K old users with 9+ MILLION old image files. So it is really bogging the system down. I am in the process of spring cleaning the old users and files. I have no idea how long it will take (a few days) and I apologize for whatever inconvenience and aggravation it causes. I'm working hard to resolve it. Linky Tools has run very smoothly for many years... I hope to have this cleared up as fast as possible.
So anyway the problem should be resolved soon. I appreciate your patience.
