Does tinypic have a thumbnail window where it displays all your images? i.e. like this
If it does, right click on the image and got save as... see what the name of the imagine is that its been saved as by tinypic..
In the case of photobucket they just use a th_ in front of the picture name you originally upload it as, but I just checked yours and it didnt work.. Check what comes up when I put a th_ in front of your imagine name.

Doesnt look like the PLA chart to me..
Anyway, if you can find that thumbnail path, this is the code you need to use
