I've experienced that exact same problem and was not able to correct it until I did as Bridget suggested she does: upload all of the pix you plan to use, then go back and write your script and insert pix where you want them. At that point, you need to "submit" after each entry so you don't lose the Blog you're working on (I guess that's how it is, anyway!
) I emailed the techie guy twice and he couldn't figure out what the problem was. He said he couldn't get it to not work, so he didn't know what I was talking about. So after fooling around with it, that is what I came up with. Since then I've been able to upload several pix without problem.
