that depends on the URL. There have been at least two other english RM forums originally hosted by fans that have been discontinued, and any link going to post in those forums can no longer work. Additionally, some japanese sites were closed as well.
Some of those resources have been made available in other links, but no one goes through the entire archive to change the old links. Your best bet is to keep looking on different link lists until you find one that contains current links.
Additionally, if you're talking not about links but about forum attachments here, then the space available per user is limited and some people have deleted older pictures - in that case you have no choice but to ask the poster here for a new link.
It might still be a problem with your phone as a lot of the links should still work - but we can't tell unless you give us examples of which links you're talking about.
Phew, sleep all day, awake all night. I don't know what to draw tonight!
Does that count as poetry? ..Is there a super fast way to test my creations in RPG Maker? Has anyone played the new Pokémon games? I'm itching to buy it but I don't think my husband will want me to after he finds out how much I spent on Christmas!
