Thanks in advance for help!
FlickrRSS displayed pictures, but when I clicked on them, they never loaded. I tried reinstalling the plugin, now it doesn't even show up in the plugins page.
Also, other plugins that I installed later don't show up.
1. double check that ALL the plugin files got unloaded
2. make sure they were all unzipped first
3. make sure you put them in the right place. If a plugin gets put in too deep a directory, WP won't find it.
