Hi,

the two errors:

QUOTE
spell_img.setAttribute('title',_lang_spellcheck );

is _lang_spellcheck avariable?if it's so it must be defined first, if not you must to quote it with single or double quotes
jscript
spell_img.setAttribute('title','lang_spellcheck');


QUOTE
textareas = myforms[i].getElementsById('textarea');

it's getElementById without (s) , but since you typed (textarea) I presume that you mean getElementsByTagName()
jscript
textareas = myforms[i].getElementsByTagName('textarea');


the images count must matches the textarea's count and it will placed next to the text area

I hope it helps
