Hawkeye are you getting a message that says the file is too large or are you getting posts with a red x on it where the pic should be? If it's comingup as too large, either change the actual size, (I find about 4x5" usually works OK) or change the resolution

I've also had better luck converting them to Jpeg files before trying to upload them.

If it says it uploded sucesfully and you getthe little red x you need to click on the box that says embed picture in post.

If that doesnt work, you need someone smarter than me to help you

Good luck!!
