Does MMS support PNG format images? I'm just wondering if android mms supports png files? I've tried sending an image, a png format, through mms. Sending is successful. However, the recipient recieves an error image. My question is, does android mms supports sending and receiving PNG format images?

Yes MMS can send png files. Even if they change the extension, it shouldn't matter as long as the mime type is in tact. and even if that is different, the image has a specific "header" that should be read by the MMS app. AFAIK, android does not change the extension, or the mime type. (at least the stock MMS app, and the Galaxy S app)

But that doesn't mean it will work with other phones. They might not have the ability to view the file type.
