Subject: Re: Display Text as Image

Hello,

your code worked fine for me, just one little problem occured.
When there are no linebreaks in the text, all the text is displayed on 
one line (that means invisible).

I found different solutions, just wanted to ask here: is it really 
necassary to figure out, how many characters a image-with can hold and 
insert the line-breaks in the text? Or did I miss some easier method for 
inserting line-breaks at the end of the image-width?

Best regards

Adriana
