Images show in admin section/creating post, but not when published

hi, i’ve upgraded to the latest version of wordpress, and use wordpress on xp, osx, and also my phone. i’ve been using the same theme for about a year and have never had issues adding images to posts.

i’m trying to post a blog now, and added images, which show up fine in the dashboard/admin section of the site. when i click “preview” or “publish” the post comes up but just says “image” in place of the actual image. the images are pictures i took on my phone and uploaded via the wordpress app. they show up perfectly when i pull up the draft of the post. i re-sized them and cut-and-pasted them to the left of the post, and everything appears the way i want it on the draft. they are just not there when i go to publish the post. what’s going on?

i am new to wordpress and have no coding background, so the behind the scenes code editing stuff is a challenge for me.

thanks for the help
