Requires PHP5+ with cURL library enabled. A separate license for Highslide JS (highslide.com) is required for commericial use.
I ran into a problem with the beautiful JS Highslide function, which allows your visitors to stay on your website, watching Twitpic pictures in a popup and the developer responded within hours with two solutions, of which one worked!
Couldn't ask for more ... well maybe I could [mentioning this because at the moment it's not in the mod.] : I agree with @crimsonguitars that a feature should be to click on the photo and show it as a larger version in a 'over layer' (don't know the tech. term).
Also, at the moment (v 1.3.1), the the module does not allow for a random display of images (on reload). It only shows either the last (ones) or a selected ID. But since it's a feed, randomisation may be impossible.
I emailed the developer who spent some time over the weekend and emailed my an updated version!
This also didn't work for me, but gave a good error message back as to why, my server was not configured with the right setting, unfortunately for me, I am on shared hosting and could not change the setting.
Again, the developer went off and did another update and now it works perfectly on my site.
Thank you for you hard work in sorting the issues I have had and I am glad I have been able to help you as well
