MySpace is an online community that lets you meet your friends' friends. You can share photos, journals and interests with your growing network of mutual friends.
MySpace allows users to custom their user profile pages by entering HTML (but not JavaScript) into such areas as "About Me," "I'd Like to Meet," and "Interests." Videos and flash-based content can be included this way.
You may enter HTML/DHTML or CSS in any text field, in line with the text content. Javascript is not allowed.
You can add transition effects and music to the photo slideshow. Note that you should keep the flash slideshow in a proper size, so that it can fit to your MySpace profile page.
When you proceed to publish the photo slideshow, choose the "Create Flash Files and Upload to Go2Album" option, and then follow the guidance to complete the publishing.

Publishing slideshows to Go2Album requires a user account. You may sign up to Go2Album if you do not have an account.
After publishing the slideshow to Go2Album, you will be prompted to the slideshow page, in which you can find detailed information of the flash slideshow as showed bellow. Copy the HTML code for embedding the slideshow to other websites or blogs.

Log in your MySpace account, open the profile editor, and paste the HTML code to the desired text field. You can preview the profile to see if the flash slideshow is properly inserted into your MySpace profile.
