Hi Martien,

You can't do that - you either send an image or you send the text. URL must
describe just one file. ImagePNG really just outputs the bytes that the
image consists of, and if you add some text to it then it is like adding
text to PNG file. Doesn't make much sense, does it?

The only way to do this is to embed the image in the HTML file. I heard that
it is possible (though I don't know if many browsers support this). Why not
go the usual route (two separate files - HTML and image)?

Regards,

Anze
