2 questions
 

First, I want to know if there is any easy way to search for duplicate pictures. For example, I have some pictures saved on my harddrive that would be appropriate for the anime/manga thread in the ENF forum. I don't necessarily remember if I have seen a particular picture on the thread already, so the only way I know to avoid reposts is to scan through all 166 pages of the thread each time I post. Is there any software that can check to see if my picture is already on the thread, or any simple way to do it?

Second, what is the difference between a Junior Member, a Member, and a Senior Member?

1. Unfortunately, there is no way to search attachments here. :( I would suggest just posting what you have, or samples of it, and another member will probably let you know if it's already been posted.

2. Junior Member = <100 posts.
Senior Member = >100 posts

I'm not sure what the distinction between "Member" and "Junior Member" is. All it really denotes, though, is your post count. There are no added benefits or differences between a "Junior" or "Senior" membership.

0 -29 posts = Junior Memeber
30 - 99 posts = Member
100 posts or more = Senior Member

Like Fango already said, these titles are soley based on post count and do not reflect any added privileges.
