I am not sure if this would be of any help to you, but some time ago I wrote a module PDF::TableX which is built on top of PDF::API2 and simplifies generation of tabular pdfs. It can be relatively easy extended to work with images, see the code below: 
#!/usr/bin/env perl -w

# this extends the regular text cell with image capabilities
package ImageContent;
use Moose::Role;
use PDF::API2;

sub draw_content {
    my ($self, $x, $y, $gfx, $txt) = @_;
    $y -= ($self->padding->[0] + 200);
    $x += $self->padding->[3];

    if ($y < $self->margin->[2]) {
        return (200, $self->height, 1);
    } else {
        my $image_object = $gfx->{' api'}->image_jpeg( $self->content 
+);
        $gfx->image($image_object, $x, $y, 200, 200);
        $self->height(200+$self->padding->[0]+$self->padding->[2]);
        
        return (200, $self->height, 0);
    }
}

sub _get_min_width { 200 + $_[0]->padding->[1] + $_[0]->padding->[3] }
sub _get_reg_width { 200 + $_[0]->padding->[1] + $_[0]->padding->[3] }
sub _get_height { 200 + $_[0]->padding->[0] + $_[0]->padding->[2] }


# the actual script to build the page
use Moose::Util qw( apply_all_roles does_role);
use PDF::TableX;
use PDF::API2;

my $contents = [
    ['http://something/something', 'img.jpg'],
    ['http://something/something', 'img1.jpg'],
    ['http://something/something', 'img2.jpg'],
    ['http://something/something', 'img3.jpg'],
];
my $table = PDF::TableX->new(2,4);
my $pdf = PDF::API2->new();
   $pdf->mediabox('a4');
my $page = $pdf->page;

$table
    ->padding(0)
    ->border_width(0)
    ->text_align('center');
$table->[0]->border_width(0);

foreach my $i (0..3) {
    foreach my $j (0..1) {
        if ($j == 1) { apply_all_roles( $table->[$i][$j], 'ImageConten
+t'); }
        $table->[$i][$j]->content($contents->[$i][$j]);
    }
}

$table->draw($pdf, $page);
$pdf->saveas('output.pdf');
