I appreciate that you have put in a lot of time and effort to create Social Gallery and make a Lite version available for free.
It is a great product, and you have been providing fantastic support.
The lightbox, however, contains a MASSIVE Social Gallery logo, complete with title tag and link, which is a bit much.
Now, I would like to support the fantastic product by providing backlinks etc. However, instead of the overpowering logo being used, I'd be happy to provide the backlink via a smaller (about 15% of current) image or a simple text link.
It would be nice if you could provide different options for the "powered by" attribution via admin UI.
In fact, you might want to include an option to completely remove the logo (even if logo is on by default - think opt in v opt out), as not providing such an option might possibly be violating WP's plugin guidelines:
The plugin must not embed external links on the public site (like a "powered by" link) without explicitly asking the user's permission.
