Is there a limit on the number of images that you can upload & display in your Blogger blog? And also does Blogger has image storage limit? As of now, you can upload any number of images in your blogspot blog as long as the image size doesn’t go beyond 2048 pixels in height or width. If the image exceeds the above criteria, then Google will store it as part of Google account storage. Generally you have 15GB of free space in your Google storage which is used by Gmail, Google Drive & Google Photos. So it will eat up space from there.
But 2048 pixel is a pretty good limit for a normal image. So you can keep on uploading thousands of images without a headache of running out of space. It is unlimited. Here is the link from Google support on that.
