aridale: Sorry, have forgotten it - I did't thought on that.
It complains about the missing image that gets drawn on the canvas of the plugin.
copy the following image in the export folder or replace it with an own (in C2 open the 'image-loading-dialog')
canvas2image.png
Wishy: I haven't implemented anything about jpg - hope that causes the error and that it's not a browser-"timeout"-error or something similar.. <img src="smileys/smiley2.gif" border="0" align="middle">
Wishy -Textsaving: Yes, I recognized that with the "Text"-object too. Is this a problem? I suppose C2 handles the Text-object a little different when using canvas2d or WebGL renderer - or this comes perhaps directly from the renderer.. (I haven't implemented anything for the renderering of text in the plugin.)
