Yes, a blog can have pictures. However, it is important to remember that not all blogs are created equal and some may not be able to support a large number of images. Additionally, it is important to consider the format of the pictures when uploading them to the blog. If they are in a jpeg or gif format, they may take up a lot of space and be difficult to view on a phone or tablet.
If they are in an image file format such as .jpg or .png, they will typically be smaller and more easily viewed.
When uploading pictures to a blog, it is also important to consider the size of the pictures. If they are large pictures, they may take up too much space on the blog and be difficult for readers to view.
Additionally, if the pictures are too large, they may end up being deleted by Blogger due to its size restrictions. It is important to keep these things in mind when uploading pictures to your blog so that you can make sure they look good and are easy for readers to access.
