Problems with inserting pictures Word 2007

I have just received an email from the Microsoft Tech Community, asking whether I have received an answer which solved my problem.
I wish to acknowledge with thanks that I have received answers to some of my questions, but not with regard to insertion of pictures. I did speculate as to whether the problems may have been caused when I installed Windows 10. The two problems I asked about in my initial enquiry did not exist for me before I installed Windows 10. I appreciate that I now have PDF functionality, following the advice I received in the first reply to my enquiry.
After the suggestion that I upload a copy of a file, I responded by sending three separate files to the email address which had been offered by Doug Robbins. These files attempted to load pictures in three different scenarios: (1) inserting picture directly into a document, (2) inserting into a table cell, and (3) inserting into a text box. In each scenario I experienced the problem that the inserted picture was not visible except when it was being stretched or shrunk.
The response I received said that the pictures were visible in Word 2003, Word 2010 , Word 2021, and Word in Microsoft 365. I responded by noting that Word 2007 was not included in that list.
I had previously been able to use text boxes very effectively (prior to using Windows 10) for my requirements, and would appreciate advice on how this functionality might be restored. I do acknowledge that the PDF files I have saved do show the pictures which I inserted in the text boxes in my Word 7 “filename.docx” files. However this feels like only small comfort, considering the inconvenience of inserted pictures not being visible in the originating Word documents.
