You don't need to escape the single quotes that delimit the literal
strings in the Javascript because you used double quotes to delimit the
whole attribute. (Even if you do escape them, you have to use an HTML
escape for them, not a Javascript one.) Removing the backslashes
clarifies the existence of a problem:

onmouseover="style.cursor='hand'; btn_img.src=''.$img.'';"

The single quotes *inside* the string being assigned to btn_img.src *do*
need to be escaped:

onmouseover="style.cursor='hand'; btn_img.src='\'.$img.\'';"

I don't see what sense this code makes anyway. If you want the cursor to
turn into a pointer (not "hand"--that's IE-specific), you set the tag's
style attribute (or use a separate stylesheet) from the outset instead
of waiting for a mouseover:

style="cursor: pointer;"

As for the image's src property, even if $img expands into something
else, I don't see how setting the src to

'.http://www.example.com/resource.'

is what you want.
