This module has some great potential! Most changes people would like to make currently have to be done within the code itself and not within the module settings, which for newbies will be very difficult.
I'd like to see these additions:
(1) Ability to enter account info within module and pull images only from that account.
(2) Ability to select groups directly within module settings
(3) The option to be able display images horizontally, vertically, scrolling, auto-sizing, background color, etc.
(4) We need some additional documentation on how to change things. I was not able to find any documentation for this module.
I think once people have these things, this module will be a knockout!
