Re-Send Blocked After Initial Post Fails

[EddieA]

Noticed a small issue with the board software.

I tried to post a message, which was blocked, because the jpgs I included were too big.

So, I shrunk them, and updated the post to pick up the new ones.

On hitting "Post", it failed to post the message, with an error along the lines:  You already posted this.

Except I hadn't, because it failed.

Cheers.
