Since I've been asked for them so often (three times and counting!), I'll 
post them to the list.  I believe I got the original code from Piddle... it's 
been a while, so I'm not too sure.  And yes, those are tab-indentations (damn 
you four-spacers!).

def PILToWX(image):
	"convert a PIL image to a wxImage"
	if (image.mode != 'RGB'):
		image = image.convert('RGB')
	imageData = image.tostring('raw', 'RGB')
	imageWx = wxEmptyImage(image.size[0], image.size[1])
	imageWx.SetData(imageData)
	return imageWx

def WXToPIL(image, mode = 'RGBA'):
	"convert a wxImage to a PIL RGBA image"
	imageData = image.GetData()
	size = (image.GetWidth(), image.GetHeight())
	imagePIL = Image.fromstring('RGB', size, imageData)
	if mode != 'RGB':
		imagePIL = imagePIL.convert(mode)
	return imagePIL
