The new WordPress 2.5.0 image upload system has several issues. I likely won’t upgrade to 2.5 until they are fixed. I like using Flexible Upload with WP 2.3 better because it…
- is faster, no need to open up a modal window to go looking for images
- fits on one screen, to get to the the button for saving the image in WordPress 2.5, you have to pick up the mouse and scroll down
- is more flexible, you can specify the size of the thumbnail on the fly
- defaults can be changed, unlike WP 2.5.
