Lowest temp I've encountered and without damage is around 15 celcius.
For those pics, they must not exceed 100 kb's.
I'll give the steps on how to upload, k?
Take pic
Plug cam into USB cable
I use Fireworks to brighten and downsize the file.
Free to download directly from Macromedia. (I'll give you the serial if you want and you can turn the trial into full ver)
As you type your reply you'll notice if you slide down, just under Submit Reply that there is a box called, "Additional Options".
And in that box is a button called, "Manage Attachments".
I hope this is what you are looking for, cause I'm gonna feel pretty tupid.
I'll continue just in case I'm on to something..........
Once you push that button, (Manage Attachments) a new window will open and a Browse button will appear. That's where you search your PC or Cam for the shot you want to upload. If the file size exceeds 100 kb's, you'll have to resize again to 100.
