What happens if you change the size mode to clip? Does it go right side up then just doesn't fit? What happens if you make the control huge so it has a lot of room?

I'd assume your images are just in a weird resolution and access doesn't know how to fit it.

Thank Adam for your reply. I will resize the heights and also look to to what properties I have set and see what I can figure out from that.
The one thing that I have done is left a link visible, so that anyone needing to view the original image can follow that path to the folder it is stored.
Much appreciate you reply thank you.

Allan the orientation of an image is usually stored in the metadata.  If, for instance, you are taking a picture with a phone it will be saved in portrait.  If you turn the phone to the side and take the picture it will save it as landscape.

Many image programs automatically adjust the pictures depending on the type of device you are viewing it from.  Most also allow you to rotate the photo and save it.  It will save in the new orientation in most cases.
So...  It is likely that it is not Access or your form for displaying the image but the image itself.

Unfortunately Access doesn't have the "smarts" built in to handle orientation.  Just looked into this for another user that wanted to rotate his forms when using a notebook.

Thank you for the replies. Very much appreciate the feedback.

I used the same camera (no phone) and same format for each image, and all the others were fine. As you say there must have been something in the way that the camera saved it, that was a little different. When I changed the odd one out to a .png file, it turned the right way up.

As for the photo on its side, that was definitely a me thing, as I had zoomed in which made the format taller than the rest. I cropped the image and again the image now display the right way up and actually better clarity than the original. Which turned out good for me.
Much appreciate your support.
