Replacing every character in a string with individual <img> tags

Hi everybody!

OK, so what I want to do is to display a string in html as images
rather than text. On the server I have individual image files a.gif,
b.gif, c.gif ... 0.gif, 1.gif, 2.gif, 3.gif etc...
So if the string is Hello, I would like to get the following output:


I would like to translate all characters, numbers and special
characters as well.

Shouldn't this be quite easy? I just don't know how to do it though...
Thanks a lot for your help!

In general, you should always post your best attempt when asking for
help.

However, I'm bored.

$string = s/(.)//g;

Surely Paul meant
$string =~ s/(.)//g;

But you need to consider if double-quote is one of the "special
characters" that you want to allow...

Took me five reads to realize you're pointing out the fact that I used
= where I meant =~

Thanks,

Special? In what sense?

Great! Thanks alot to all of you!
But... I've now realized I have another problem...
With special characters such as Ä, I decided to go for filenames such
as AE.gif to avoid problems with encoding, and first tried a
$string =3D~ s/Ä/AE/g;
prior to the above, but then of course I'm left with two images (A and
E) instead of the desired AE.gif. Is there a way to avoid a lot of if
statements here?

Use a hash.

my %special = (
'Ä' => 'AE',
'Ö' => 'OE',
);

s/(.)/''/eg;

In the senses that probaly isn't parsed the intended
way by most HTML readers.
