Hoffa, is there any way to get an offline converter, or is this only online?
Actually there is, and there have been one since TI released Scripting Tools. I had never noticed it (actually I did, but wasn't sure what it was for), but the button for "image serialization" actually copies to clipboard the TI.Image of an traditional image format (PNG, BMP, nearly anything).

Lol nice jim :P. Also we released Lua makers before TI did :P. On top of that on TI site good luck finding the Lua tool from the front page. It's well-hidden.

This is the link to it http://bwns.be/jim/convert.py .
You need pythonmagick to use it (Linux users can use the package manager to install it).

Usage: convert.py infile.png data.txt

Hi Hoffa,
Can you please send me the Lua script for simple_image_viewer.tns?

I try to use the functions directly by I got an error

gc:drawimage (image,0,0)  attemp to index global "gc" (a nil value)

Thank you

Joaquim

jboavida, you need to put gc:drawimage (image,0,0) inside on.paint, like this:
Code: (Lua) [Select]
function on.paint(gc)
    gc:drawimage (image,0,0)
end

on.paint get called every time the screen gets/needs to be redrawn (for example when you open the program or run platform.window:invalidate()

Everything that uses gc should be called from on.paint. I recommend you to read  the tutorials at http://www.inspired-lua.org/category/tutorials/starting-in-lua/ , they will help you understand how nspire Lua works.

The website in the first post is now filled with pictures of birds and the hoffa.zzl.org site I had been using a while is now down.

So what're my options for converting pictures of .png into TI Image with support for transparency (any color)?

I've been fairly busy in the Lua world, I just don't post a lot ^^
And I'm sure others do the same ;)
