Hi, I think I understand what your want & I'll try to upload something soon. Do you get any options anywhere to specify the font & colour for the lines of text that appear? Alternatively, would it be possible to upload your css here onto the contest? Thanks.
I also notice you'd like to retain the flexibility of having the lines of text as editable by yourself - understandable. Have you considered just not using the text line feature & instead having the text on your background? You could potentially have many more possibilites, albeit you lose the effect of the text moving across the image. Perhaps if you were supplied a layered Photoshop file so you could edit the text from in there & save a new image if required?
