We have received a few questions about how to sort and arrange photos on your blogs. Here are a few pointers:
When you are creating a post, place your cursor where you want the images and click the <Add> button
Then select <Media>:
This will show you all of the image you have already uploaded to wordpress. If you want to add other images (JPG or PNG files work best) you can either drag and drop them on this window or click the <Add New> button and select the files from your computer.
Once the images are uploaded, you can choose multiple images to insert into the post. the order you click on them will be the order they appear in the post (but you can also edit this later). Once you have selected in images for the post, click <Continue>
This will bring you to the layout page which allows you to select different layouts. <Individual Images> simply places the images in a vertical list on your blog. The other formats will arrange them in a variety of ways and offer you other settings to tweak the design.
Once you see the images in the preview, you can also click the <Edit> button to change their order. When you like the arrangement click <Insert> and it will place the images into you post.
