I've come across the same problem with 99.2alpha. A comparison with earlier
known-to-work versions reveals a return where none had been previously in
sub find_unique in latex2html(.pin)

sub find_unique {
    local($image1) = @_;
    local($imagedata,$image2,$result,$key);
    local($/) = undef;

    if(open(IMG1,"<$image1")) {
        $imagedata = <IMG1>;
        close(IMG1);
    } else {
        print "\nError: Cannot read '$image1': $!\n";
        return; 
#       ^^^^^^
    }
 
    foreach $image2 (keys(%image_size)) {
<etc, etc>

Commenting this return out causes images to appear as they should, when
referred to by a URL. There may be other effects and indeed this part of
the sub could bear re-writing to prevent opening of such a file in the
first place - or perhaps there should be an earlier test to prevent this
sub from being called when dealing with an image that is referred to be
URL?
