can't delete unwanted photos on my page, I followed instructions but there is no delete option

Thanks for the problem report. It sounds like you are trying to remove images which you did not upload? In which case, the guidance in  https://help.imdb.com/article/imdbpro/manage-your-imdb-page/manage-your-images/GYJLH267T2DMYJ53?ref_=helpsrall#delete applies:

You can also request deletion of images which were uploaded by IMDb editorial by clicking "Report this", though these requests will be vetted by IMDb. Note that if there are other people tagged in the image with you, you cannot delete the image in its entirety. However, you can un-tag yourself so that the image no longer appear in your images though it will continue to appear in the other tagged people’s galleries.

The “Report this” link is actually now an icon which resembles a flag.  We apologise for the lack of clarity here and we will arrange to have the guide updated. 

Hope this helps.
