Posting? Can't attach pics..

I know this sounds really dumb, but on every forum I am on, I am getting this message that "Sum of Attachments" "I have exceeded, etc."

I can't post pics, It is asking me to delete all attachments and somehow is making me "store" anypics from any threads I have commented in.

is it a Mac thing...cause it seems like IN all the forums I have this issue on now

 

two words...

Thank you
