Hi pault36225916,
As per my understanding, you are using Acrobat X and want to add images directly into the PD document (correct me if I am wrong, please).
If so, then you can follow the steps given below:
1. Go to Tools > Content > Edit Object Tool
2. Right-click the page and choose Place Image
3. Choose any of these image formats: bmp, jpeg, gif, pcx, png, jpeg2000 or tiff
4. Select an image file and click open.
A copy of an image file appears on the PDF page with the same resolution as the original one.
Hope the above information helps you.
Let me know if you need further assistance.
Regards,
Anubha
