[SOLVED] Uploading image?

[Cuteless]

Anybody has some advice on writing custom module for uploading images to server? The uploading part is what I'm interested.

Virtually anything you do involves sending data to the server,
so you just need the appropriate message.

Here's one approach:
It may or may not be the best way, but it's the first thing that came to mind.

For a model you can use the Union Chat Room example.
Just replace the chat that's sent with your image data.

You'll need a module to receive the data.
It can either be a server module, or a room module.
This example uses a room module, but a server module example would be similar.

From the client side, use something like this:
msgManager.sendUPC(UPC.SEND_ROOMMODULE_MESSAGE, roomID, "image-data", "thedata|"+imagedata);
(A server module message will be similar.)

Now that straightforward call might need some preparation for a couple of reasons.

- Image data is probably binary, so you might want to convert it to some text-form representation,
such as hexadecimal or base-64 encoding.

- Image data can be be large (as in megabytes, etc) so you might want to break it up into parts.
Just add more arguments:

msgManager.sendUPC(UPC.SEND_ROOMMODULE_MESSAGE, roomID, "image-data", "part-number|" + p + " of " + n, "thedata|" + imagedata);

Then you need to write the receiving code in the module on the server side
which decides what to do with the image once it has it.
