Creating small photos, thumbnails

You can upload photos or graphics files into your WordPress blog.
Make sure use one of these image types: .jpg/.jpeg / .gif / .png
to a post or page on your WordPress blog.
Most images from the camera saved your computer either jpg or tiff file. Some DSLR has raw or dmg files too, which they are usually very big size images.

If you do not want to put large image on your blog, you can use thumbnail option.

Upload Images from Your Computer

When you are uploading image to a WordPress site, the default large size is 1024. That is pretty big if you like to view a photo on the web.
However if you are uploading a photo from your camera, there is a good chance WordPress blog will give you error message. It will not upload the image, unless you change the size of the image or your media setting.

I would recommend to make  950 size images for your blog before uploading them. This can speed up your blog page and you do not have to fill your hosting  package with lots of large image files. If you use too many large images on the blog, your website will be slow down quite a bit. So you have option to make large images clickable with either thumbnail or small sizes as well as you can re-size all your images before uploading to your site.
