Hello to all, I would have need of knowing some things.
I am trying to create a generator of sign basing to me on the code of: "
Avatar Generator"
I must simply replace the images with those which I will use like base in order to create the companies.
The page will have to be raggiungibile directly gives
/sign_generator.php.
I am using this code:
<?php

but when I go to visit the page gives back to me:

Font size may not be reduced further, try to insert a shorter text
or

Font size may not be reduced further, try to insert a shorter text
instead in the folder two rows are present these:
- background_1.png
- background_2.png
You can help at least giving a input me in order to finish this modification to me that in my situated one serves enough?
I say thanks in advance payment all :mrblue:
