I'm not sure what yo mean by the plugin allowing you to change the template. Do you mean theme? If so, regardless of theme, the link appears using this plugin.
What I have been hoping for is that in your plugin that a link (corresponding to all photo/graphics thumbnails (not thumbnails that represent links to live websites) being used in your plugin can either have no link showing or replace the link with a title.
The reasons for this is that the link for a photo or graphic
1.)Can be long and attractive. (i.e. http://awebsite.com/wp-content/uploads/2012/07/Mrk41GothamWebsite.jpg).
2.) In addition, as far as web security goes, your plugin provides a clue to hackers as to the structure of your site and graphics files are typical targets. Yes, one can also look this WP structure up but why make it easy for a hacker to know your structure and file naming conventions? Why do people hack? Who can say, the best rationale I have heard so far is, "because they can."
Shrink the Web-The other thing that is a bump in the road as far as using this plugin goes is forcing a stop and extra step by requiring people to halt progress, address a third party-Shrink the Web and give it consnet to continue. It seems like the type of impedance that causes people to cease. If nothing else people might think it is a hijacking site.
Disable Plugin CSS- this is a nice, much appreciated feature. In my case, I simply want to change the default font to the same font the current theme uses. This apparently can't be done in the Layout Settings page. The css you have designed here is nice. It's what makes this plugin so appealing. If you disable it, that nice formatting is gone and it doesn't seem to hand-off style (font type, in particular) to the theme.
In the meantime of waiting to see if the above link/style issue might be something that could be changed with your plugin, I found another plugin that does what I was hoping yours could/would do for pictures/graphics. It is called WEBPhysiology Portfolio. You might want to check it out. It looks and operates similar to yours and works nicely for photos and graphics with no link(unless you want it). It's been a nice solve and doesn't involve the Shrink the Web step.
Thank you Dan. I hope this helps.
