Blogger only allows you to upload 5 images at a time. This is a big time hassle if you're trying to upload a ton of pics. To get around it, just add the Drag Drop Uploader add-on to Firefox.

Once added you just:
- open the folder with the images you want to upload
- highlight the images
- drag the images into the upload images box
- click the upload image button
1. Open folder and highlight images.

2. Drag and drop into blogger image uploader.

3. Click the upload image button.

*Note*
The Drag Drop Uploader tool works with all sites, but I've only seen it go over the max number of photos in Blogger.
