Hi mwells4654. Okay, let's work this from your original computer. We'll take this stepwise and try to set you up right.
It is true -- a post without any text in the main post window (eg, with just photos attached) will not be allowed to display. This is a software issue. Place an introductory word or two in such cases. Placing a title does not count toward the "at least 3 characters" rule.
Now, your specific problem... Do you type and see the words sequence properly in the main entry window? It just gives you the "must contain at least 3 characters" dialog after you hit 'Submit Reply'?
Please post back to this thread and let me know about that last question I asked you.
