Uploading a picture in your blog post is a must, otherwise the article will give a dry look to the audience.
When uploading an image file, do not forget to write the ‘Title’ and ‘Alternate Text’ in the given space. Remember that writing a caption for your picture also proves to be helpful.
Do not upload random images but choose the images that are perfect for your posts.
You can find all kinds of images on different search engines and there are many websites that offer these services for free or charge a certain amount of money. Remember that, you should never use copyrighted or trademark images and look for royalty free images. There is no need to worry as royalty free images are in abundance.
If the size of the image is not large enough for your post then you should resize it, there are plenty of free softwares, which offer these facility.
