What Nic said. If you are loading content over the internet directly into a cell, its got to go on another thread. There are numerous options you can use:1. Use another thread. Get the loading off the main ui thread.2. Cache data locally. Don't go get the same resource more than once unless you really need to.3. Do something async, though, this really goes back to "Use another thread." I've got an article introducing the uitableview coming out where I talk about this issue.
