Here's the situation:
I'm using the sitewide tags plugin to display posts from sub blogs on a main, or "tags" blog.
In my network installation, in the main blog, using the SWT plugin, I want to display a loop of images (and the title and some meta info, but I understand how to do that) from posts in my sub blogs. I want the loop to display the post thumbnail first, if that's available. If that's not available I would like it to pull the first image. If that's not available I would like it to pull the avatar. If none of these are available, then I don't want the post to display.
Here's the thing. I've seen solutions to some of the individual things I'm looking for, but haven't seen any with these fallbacks. Also, I'm using a grid with some pretty tight parameters, so I created a post thumbnail size to fit. I don't understand how to also get either the first image or avatar to also size and crop correctly.
I also want the images to link to the post.
Hope this all makes sense.
Thanks very much!
