Blogger is one of the most famous blog publish system which was owned by Google since 2003. One of the most popular feature is that you can easily embed slideshow or online videos if you have uploaded the slideshow or the video to a certain server and got a section of embed code. Here we can see how to embed slideshows created by Photo Flash Maker Pro and your favourite YouTube videos.
Photo Flash Maker Pro can create stunning slideshows with basic and advanced themes. And both the slideshows created with basic and advanced themes can be embedded in Blogger with a few clicks. Before you embed the slideshow in Blogger, you need to upload the slideshow to go2ablum. You need to sign up an account of go2ablum at first, it’s free. Please visit http://www.go2album.com.
When you publish the slideshow, please select Create flash files and upload to go2ablum. After you uploaded the slideshow successfully, you will be led to the slideshow page automatically. In the opened page, copy the the embed code of the slideshow.
If you want to embed a YouTube video, just do it in the same way.

Step 1 - Click on Create, under the Posting section
Step 2 - Paste the code into the text box (Right-click in the box and choose "Paste" or just hit Ctrl-V)

It’s recommended to adjust width and height to 400×300 since blogger won’t accept width more than 400.
