Google/Blogger Image URL Parameters

Google/Blogger Image URL Parameters

This is an effort to document what is known about Google's (Blogger's/Blogspot's) image URL parameters. Some of these options were taken from existing first or third party documentation (see the links at the end of this document), but the majority is based off my own investigations.

Where to use them?

  • On Blogger's image URL's: 2.bp.blogspot.com/-OF7u67HQE1M/VHc8S8qJTDI/AAAAAAAACxI/UD-11c63diQ/s1600/005.png
  • On just about any googleusercontent image URL: https://lh3.googleusercontent.com/Jvmz11cLrvNIHG_LWjVO9B-UV2IN4Cfk1pycbhWZl6IriMgCAGCOFuBRtoHaiZ6xeVGqCugZcCql=w176-h176-n-o

Replace the bolded parts with the parameters.
