This one has been a long time coming and today I finally decided to just go ahead and get it live. I think this is an update that the bloggers amongst you that take a lot of pictures are going to appreciate, a lot.
TAB 1
The basic step is as before, click on the IMG link when entering your blog entry. Instead of a simple drop down list of photos, you'll now be presented with a table with (by default) the last 50 pictures you took. If this looks familiar, it's because it's very much the same look and feel as the my photos page, where you normally edit your pics.
Improvements over the old system:
- thumbnail, which on hover will show you a bigger size
- option to insert multiple photos at once without re-opening window
- sorting of columns to make finding pics easier
- filtering by tag or country to really make finding pics easier
- add captions to your photos using the little graphic (or go captionless using the text link)
- choose between multiple sizes
That's the main set of changes when it comes to the Travellerspoint photos.
TAB 2
If you're a Flickr user, and just can't break away from there no matter how hard you try, clicking on the tab 'From elsewhere online' will (for now) give you two options. Flickr, and Link. Click on the Flickr heading to enter your Flickr username and watch some serious magic take place 
Okay, well maybe not magic, but it's pretty nice. Essentially, you'll have access to all your public Flickr pictures in the same format as the Travellerspoint ones, as well as a few filtering options.
The Link option allows you to enter a photo from somewhere else online and enter it that way. Nothing too fancy.
TAB 3
The third tab gives you the option to upload a photo right within the pop up window. Could be useful if you don't want to lose the blogging groove you just happened to have found 
As there's a lot of changes involved here, let me know if you hit any issues. I know there might be some small layout issues in Internet Explorer (what's new there!?) on Tabs 2/3, but there could be other less obvious issues too.
All in all, I think this significantly improves what is probably the process that most people have asked to have updated in the past year!
