This post describes the upload method where you actually upload pictures to your posting. You have to describe the pictures and identify what each are. They are always uploaded after ALL of your text.

To comment with text between pictures you need to have the images elsewhere on line. Instead of uploading them here you need to link to them to make them appear on your posts. So you can write a description add a picture by linking to it's online location then write more then add another picture and so on.  

That is addressed in this post.

Hope this helps explain the process if you have other questions just ask. This is using a computer I'm sure phone and Ipad are similar and maybe others will chime in with those specifics.
