I switched to Flickr from photobucket, and that seems to work fine once you get your head around how to use it. As far as I can tell, you have to drag and drop your pics to the "Camera Roll", then individually change them to "Public" by clicking the icon in the bottom left corner of each thumbnail, which opens a drop down box (otherwise they won't display when you post a link). Then click "select all" and a pop up box opens at the bottom of the screen, where you click "Add to Album", then select whichever album you want them in. Obviously you need to create an album first. It sounds long winded, but after a few attempts it seems pretty quick and painless. Obviously I might not be doing the procedure as efficiently as possible, this is just how I've got it up and running for me.
When you want to insert a photo on here, just select it from your album, then copy and paste the URL straight into the body of your text.
I hope that helps anyway
