Gallery2 (g2) Widget Support
After changing my hosting provider a few months back I finally got around to putting my image gallery back online. I installed F-Spot on Gnome and organised a bunch of my photos (not all of them yet) into Tags. I then put a fresh install of Gallery2 up and uploaded them all though F-Spot. Simple enough.
Next however, I wanted to display a random image in the sidebar of this blog which is hosted on the same server but on a different domain. I picked up the line of php from the Image Block section of gallery and tried to put this in one of the text widgets.
Text Widgets don’t support PHP however.
I looked all over the Web and couldn’t find a solution; I tried a few different widgets but none of which seemed to work. I even tried a widget which lets you run PHP Execs but it gave a security error generated by Gallery2.
In the end I came up with a solution.
I inserted the PHP External Image Block code generated by Gallery2 and put this line into a .php file (I called it photos.php and located it in the wp-content directory). Then I created a new text widget and setup an iFrame with the following aspects:
src=”/wp-content/photo.php” FRAMEBORDER=”0″ MARGINWIDTH=”0″ MARGINHEIGHT=”0″
The result is the Random image that you should be able to see to the left. It’s hardly ideal but seems to work.

A little update to this one.
You may need to set a width - it was breaking my site in IE6 without one. In which case just add this to the iFrame bits (so width=”150″ is what I have.
Also you will need to get the image to open in a new window. To do this, change the part in photos.php to something like this:
