Sorry about that.

Thank you for the 2.5 build!

I noticed as a consequence to trying it out that Image.show() has 
changed on Windows XP (all 'nt' versions, it seems). The behavior of 
cmd.exe if command extensions is enabled (which it is by default in 
WinXP) is such that a command like
"start /wait %s && del /f %s" % (file, file)
does not in fact wait until the application invoked by the start has 
completed, but returns immediately. So it seems that the 'del' is 
executed before the image has a chance to display, at least in Paint 
Shop Pro, which is what I'm using. I suppose it would be the same for 
other viewers, though I haven't yet tried them.

The old method did leave a lot of temp files around, which was a minor 
annoyance, but at least it would display the image. I've restored the 
2.4 behavior on my computer as a getaround, pending a better solution.
