Blogger images: uploading, storage and unsupported image URLs

Images make posts better and heavier. Blogger has changed how it stores them, and old posts may need a check.

How images are stored

Blogger's help page on image storage says that, for reliability, Blogger switched to a new domain for serving images, and the change has been extended to images posted in the past. Where possible, old image URLs on your blog are converted to the new format. Images uploaded at blogger.googleusercontent.com have URLs that do not expire; edits in Google Photos do not break them; they appear in Google Takeout for the owner; and you can find and manage them in the media manager at blogger.com/mediamanager.

Unsupported image URLs

Some images cannot be moved automatically. Images hosted on third-party sites and old Photos1 images are not affected by the change. If you want to keep showing an image that Blogger cannot convert, download it, upload it again and replace it in the post. To find them:

1. Open Settings.
2. Under Manage blog, click Manage unsupported image URLs.
3. Select a post. In the HTML view, the unsupported URLs are highlighted.
4. Download the picture, upload it again to the post (this creates a new, supported address), and delete the old one.

If the link is not visible, Blogger says that your blog is not affected.

Add pictures well

• Resize photos before you upload. A camera photo of several megabytes slows the page. A width of 800 to 1200 pixels is enough for most blogs.
• Name the files in plain words before upload (rajma-recipe.jpg), not IMG_4021.jpg.
• Click the picture in the editor and choose Edit to add the alt text (a longer description) and a title (a short one). Blogger's SEO tips recommend this so images are searchable and accessible.
• Use the image lightbox in Settings, under Posts, if you want images to open in an overlay on click.

If you cannot upload

Blogger's troubleshooting page says: turn off the popup blocker or add Blogger.com as an approved page, and in the Add Images box make sure to click Select. Also try the other checks: reload, update the browser, clear cache and cookies, try a private window and turn off extensions.

Copyright

Use pictures you made, pictures you have the right to use and pictures with a licence that allows it, and credit the author when the licence asks. A photo found through a search engine is not free to use just because it is easy to copy. Ad programmes check this.

Mistakes

1. Huge uploads that make mobile pages slow.
2. No alt text anywhere.
3. Hotlinking images from other sites (the other site can delete or change them).
4. Ignoring the unsupported images list on an old blog.
