Go to your album, click and open the photo you want to delete, it will open up into a larger version of your image. Then go to the link under it that which says Delete Photo, that will remove the image. Videos should be used via YouTube or Google, we do not allow video uploads because of the space and bandwidth they consume. Here's the link to copy/past the code from one of those sources, it will automatically be added to your videos.
To add an image into your center page simply click the edit button and then the editor has an auto upload utility that's depicted with the little photo frame icon which will allow you to add an image; just must make sure to click on save after you have added the content into the box. If for some reason the upload utility will not allow your image, it may be because the file size is too large. This help section has a lot of additional info on setting up your page etc. that may also help.
Thank you very much for responding. The deletion process worked very well. I reckon I need to start scrolling down the page to see the other options like the very plainly visible DELETE . As for the videos, I will have to wait until I return home, as the military here have restrictions on video channels like YouTube and Google.
Thank you again for the quick assist. Earlster
