Photobucket works well for me. You can link them easily or if you make your free account "PUBLIC" anyone can access it. One account per email address and it does have a size limit. I have 6 accounts with them using other email addresses within my family. With Craigslist, there is no need to have giant size resolution photographs. I usually resize them to 800 wide or less. With photos of 800 wide, you can load up Photobucket with many many photographs.
These photos are only 800 wide and do great on Craigslist.

You have to know the code for html to make it work on Craigslist or Ebay.
