I'm probably overlooking something obvious, but have not done
this before. How can I get the PNG into Python source code so
I can use PNGs? By the way, I am using PNGs with transparency.

I am just doing this in my script for PNG's, i.e. nothing special.

Are you getting an error/exception or is just nothing added to the images.py file?

it should -- are you sure it tried? does that script find your pngs? Where there any other pngs that got converted?

imp2py stores images as png -- so what that means is that if they are already pngs, they will be moved in directly, rather than being unpacked into a wx.image, and then re-converted to a PNG.
Which brings up a thought -- it would be nice if img2py could store images as either png or jpeg -- jpeg is more suited to some image types.

No errors, I am just getting something that doesn't appear to be the
right encoding for the PNG image. What I get is this (the PNG is
called couch_25.PNG):
There should be more than just that "iVBORwo=" section.
I tried it again doing it from the command prompt with no flags,
and got the same thing. Again, it's a 25x25 PNG with transparency.
Now that you and Chris say it should "just work" with PNGs, I
am confused but perhaps I can try other PNGs and see if it is
somehow related with this PNG.
Thanks,

Are you getting an error/exception or is just nothing added to the
images.py file?

Try with the SVN version of img2py. IIRC Robin fixed this issue some time ago.
...and now it is just providing the PyEmbeddedImages alone. But
I had been using these get[imagename]Bitmao() methods to actually
get the bitmaps into my app, so what should I now do?
(On a side note, that script I am running is not converting *all* the
files in the current folder through py2img. It appears to be entirely
leaving a few out for no reason I can yet figure out, and this is unrelated
to what kind of image it is (JPG, PNG, etc)).

Possibly answering my own question... I don't see why I really need
these methods other than they were put in as a convenience. I should
be able to just refer to the image in this way, right?:

Yes, it had converted all the other non-PNGs fine, and found my PNGs
but just encoded it as "iVBORwo=" without anything further.
But in another post here I replied to Andrea letting him know that the
SVN version of img2py does create the full PyEmbeddedImage
correctly, so problem solved I think.

For the record, the problem was that the files were not being opened in binary mode, and so on DOS if there was a EOF marker (Ctrl-Z) in the binary data stream then that is where the data reading would stop.
...and now it is just providing the PyEmbeddedImages alone.
Because you fetched the trunk version which has that feature turned off by default. The version of the code on the 2.8 branch has the feature turned on by default for compatibility with the older version of img2py.
But
I had been using these get[imagename]Bitmao() methods to actually
get the bitmaps into my app, so what should I now do?
IIRC, you can use -f to turn it back on.
