For one, both file form input boxes are named "file". Try naming them
"logo_file" and "citymap_file".

You could also use records marsalling to eliminate the redundant coding
both on the form and map_add: (Not tested)

<form action="map_add" method="post" enctype="multipart/form-data">
<dtml-in expr="['Logo', 'Map']">
<p><b><dtml-var sequence-item></b></p>
<input type="hidden" name="images.id:records" value="<dtml-var
expr="some expr">">
<p>Title: <input type="text" name="images.title:records"> </p>
<p>File: <input type="file" name="images.file:records"></p><br>
</dtml-in>
</form>

Then map_add could be:

<dtml-in images>
	<dtml-call expr="manage_addImage(id, file, title)">
</dtml-in>

or a python script:

for img in context.REQUEST['images']:
	context.manage_addImage(img.id, img.file, img.title)
