[JavaScript applications, like this one, run wonderfully on mobile devices like the iPhone.]

AJAX SLIDESHOWS (works on ANY web site & even locally, if you use Firefox): Content of the htmlPicfileLASTNAME.txt files (make one for each person/customer, by LASTNAME -- upload to a folder named uploads on your site or subsite).:

<div><p>&nbsp;</p></div>
<ul id="widget" style="overflow:hidden; margin: 50px auto; width:500px; height:405px;">
<li style="float:left; list-style:none; margin: 0 5px; margin-top:180px; cursor:pointer;"><img id="prev" src="uploads/prev.png" /></li>
<li style="float:left; list-style:none; margin: 0 5px;"><img height="400" width="400" id="slideshowX" /></li>
<li style="float:left; list-style:none; margin: 0 5px; margin-top:180px; cursor:pointer;"><img id="next" src="uploads/next.png" /></li>
</ul>
</ul>
<center>
<div id="div1" style="display: none; background-color: yellow; text-align: center;">
<b>first</b>
</div>
<div id="div2" style="display: none; background-color: yellow; text-align: center;">
<b>second</b>
</div>

<div id="div3" style="display: none; background-color: yellow; text-align: center;">
<b>third</b>
</div>

<div id="div4" style="display: none; background-color: yellow; text-align: center;">
<b>fourth</b>
</div>
</center>

(end content)

ALL YOU NEED TO CHANGE IS THE "X" in "slideshowX" (in the image (img) id of the second line item (li)) -- to a different number for each customer.  THEN also the images for each customer (which are to be 400 X 400 pixels) would be named:  X1.jpg, X2.jpg, X3.jpg, etc. (upload to THE uploads folder). (The number of jpgs matches the number of divs in the Content, named: div1, div2, ... divN).

Change the text "first", "second", "third" and "fourth" in the divs to the text you want for each caption, FOR EACH customer (i.e. in each of the customer txt files). 
NEW FEATURE (compared to old version): The program has now been adjusted to allow for any number of images/captions.:
The way that works is by adjusting the number of div1, div2 ... to be the same as the number of images you have for that customer/person.
Presumably you would have no trouble deleting or adding these sorts of things (and having the divs named sequentially, div1, div2, ....): 

<div id="div4" style="display: none; background-color: yellow; text-align: center;">
<b>fourth</b>
</div>

JUST VIEW THE SOURCE OF THIS PAGE, Copy it, AND PASTE that INTO NOTEPAD AND then SAVE AS [whatever].html -- have "Save as type" selectbox set to "All Files" when you save it. With THAT, and making txt files for each person and uploading them to the uploads folder and uploading properly named 400 X 400 images to the uploads folder, you have every thing you need to have this application for yourself. (The [whatever].html file is to be one level up from the uploads folder, i.e. in the root of your site or subsite.)
