Pics problem....

I'm having issues posting pics now...
Posted several last night, went to post more. Couldn't do it.
Same thing tonight!!!
Says I'm missing a "Security token".

I HAVE been feeling a little insecure lately but I doubt thats it.

Whats a security token and where did mine go???

 

Your pics are too large....

 

Really??? Thats it?
It always told me if they were too big before...and I'd just go resize the pics.
Whats that security token thing all about?

Regardless...thanks, and I'll give it a shot!
