Moving this post to the correct forum for you, the help forum as per its description is for people needing help -->installing<-- interfaces..
The file size limit is 6mb in our downloads database which is where your interface should go. If your trying to attach it to a forum post you shouldn’t do that as it defeats the purpose of us having a downloads database and the forum limited to 2mb as I think you already found out. In our downloads area if you upload something there you can have 6mb for the file and up to 2mb per each screen shot.
Check our FAQ
http://faq.eq2interface.com for more information on uploading and maintaining your interface in our database.
Good Luck
