I am using Flowplayer 3 and I have been trying to figure out how to assign a custom canvas images per video. I know that you can do it global in the SWF Tools settings, but I need the canvas image to be different for each video. In order to make the commercial version were I had to put my in params each time I used a video through swf tools, for example:

[swf file="myfile" width="350px;" height="226px;" params="{key: 'mykey'}";]

This worked to get the Flowplayer logo to be removed so I tried to add some things into the params to change the canvas, but everything failed. I looked into the module flowplayer3.module file and I can see where canvas is assigned, but that didn't help me to figure out what to put for code with my video so they could have custom canvas images. I hope someone can help me with this.
