Why not just do....

OK! I do think that we can probably help you to figure this out now. You probably want to do it a bit differently, since as far as I can tell you’re doing things exactly the opposite of how most people do them in MODx (which is not wrong; it’s creative!).
You can pass a parameter to a snippet just by using the following syntax:
[[mySnippet? ¶meter=`myValue`]]
So you don’t need a TV with an eval to do that. What I would do is to store the slideshow folder path in a regular text TV and then just pass its value to the snippet. So if I understand what you want to do correctly, your snippet call would probably be:
[[ImageSlideTags? &sld_fld=`[*slideshowFolderPath*]`]]
Also: You don’t need to declare $base_href as a global var and all that; just use something like:
$modx->config[’base_url’]. "assets/images/slideshows";
$modx->config[’base_path’]. "assets/images/slideshows";
