That's doable with custom coding - I'm assuming you want it to be like the first image that has a caption, but backwards so the text shows on hover.
By the way, I really like your paintings. 
hi Adam,
yes, here are the instructions. it's just not entirely clear to me if i'm doing it right. they're not written for a dummy like me 
and i don't understand most of it. that said, i installed another jQuery plugin, was able to follow the instructions, and it works fine (fine enough). but this one is different...
thanks so much for replying!
How to install
1. Upload cubeportfolio folder to your server. This folder contains all of the assets of the plugin.
JS
CSS
images
2. Include the following files in your <head> section of the page. Please ensure that all of them have the correct path:
<!-- load cubeportfolio css file -->
<link rel="stylesheet" href="cubeportfolio/css/cubeportfolio.min.css">
<!-- load latest jquery from google resources-->
<script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js"></script>
<!-- load cubeportfolio jQuery plugin -->
<script type="text/javascript" src="cubeportfolio/js/jquery.cubeportfolio.min.js"></script>
Be aware that Cube Portfolio plugin requires jQuery 1.7+. If you already have jQuery on your page, don’t include it second time.
3. Insert the HTML structure below to the <body> section to build the markup (don't forget to update images path!).
For more complex structures please check the templates folder.
<div id="grid-container">
<div class="cbp-item">
<a href="#" title="custom title 1">
<img src="path/to/img1" alt="custom alt 1" width="100%">
</a>
</div>
<div class="cbp-item">
<a href="#" title="custom title 2">
<img src="path/to/img2" alt="custom alt 2" width="100%">
</a>
</div>
<div class="cbp-item">
<a href="#" title="custom title 3">
<img src="path/to/img3" alt="custom alt 3" width="100%">
</a>
</div>
</div>
4. Initialize the Cube Portfolio plugin. Usually just before the closing body tag: For more info about options go to Options section.
<script type="text/javascript">
jQuery(document).ready( function() {
jQuery('#grid-container').cubeportfolio({
// options
});
});
</script>
As an alternative initialization, the options can be placed as a JSON object in the HTML data attributes for grid container:
<div id="grid-container" data-cbp-options='{"rewindNav": false}'>
<div class="cbp-item">
<a href="#" title="custom title 1">
<img src="path/to/img1" alt="custom alt 1" width="100%">
</a>
</div>
</div>
Options
There are numerous options that can be added to configure Cube Portfolio behavior. To set an option, you must add it to the initialization block of code.
<script type="text/javascript">
jQuery('#grid-container').cubeportfolio({
// place here the options. Don't forget to separate them by comma
});
</script>

Thanks for the instructions, @MJB. Unfortunately, it would be extremely difficult to get a script like this to work with Weebly because of the extra files you need to upload.
You'd need to make folders and upload them in the theme editor, however the URL of all the files would be different than what their scripting expects. This means you'd need to customize their javascript so every file URL is correct, which is made all the more difficult because they've given you minimized JS.
Minimized JS loads faster because it's smaller size, but it's basically unreadable to a human so editing it would be very hard.
I hate to be the bearer of bad news, but I wouldn't recommend trying this one. 
Have you checked out some of the media apps in our App Center? We have some different slideshow and image apps that could give you dynamic content, but without all the headache.
Most of them should be found in the Tools category here:
whoops, i was looking for your response and managed to miss it. sorry about that; disregard my nudge and wink
so yes, that's one thing, i'd the content to appear on hover (the way it is now seems a bit ass backwards, no?). so i'd like to fix that. but most preferably, i'd like to include actionable content once someone actually clicks on one of the images (share, ask about this painting, buy, etc.).
that's why i was trying so desperately to get the cube portfolio to work. see this sample: cube portfolio
that’s my dream portfolio presentation, but i can scale back my wish list to something between the cube portfolio and the one i implemented. i just don’t know how. most of my pleas online have been met with silence or non-english speaking solicitations. if i can’t do this myself, could you cue me into how to ask for what i need? or do you know of someone i could hire to futz with this?
thanks so much Adam, you’ve been really helpful. and thanks so much for the kind words about my work!
