To Create A Generator Of Images Based On Avatar Generator
-----------------------------------
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: "[b]Avatar Generator[/b]"

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 [b]/sign_generator.php[/b].

I am using this code:

?>[/code][/spoiler]

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

[code linenumbers=false]Warning: imagecreatefrompng() [function.imagecreatefrompng]: 'images/sign/base/' is not a valid PNG file in /web/htdocs/www.makingart.org/home/sign_generator.php on line 56

Warning: getimagesize() [function.getimagesize]: Read error! in /web/htdocs/www.makingart.org/home/sign_generator.php on line 57
Font size may not be reduced further, try to insert a shorter text[/code]
or

[code linenumbers=false]
Warning: imagecreatefrompng(images/sign/base/background_2) [function.imagecreatefrompng]: failed to open stream: No such file or directory in /web/htdocs/www.makingart.org/home/sign_generator.php on line 56

Font size may not be reduced further, try to insert a shorter text[/code]

instead in the folder two rows are present these:

[list=1][*]background_1.png
[*]background_2.png[/list]

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:
