Both my daughter and my wife's sister regularly send me emails with photos taken on their I-Pads, which I have so far been unable to 'copy and paste' into my pictures folder. I am using Windows 7, in case this makes any difference to replies. Any help would be appreciated.
OK i want to answer the orginal post because you mentioned copy and paste into a folder.
When images are sent via email, you must download the image and then save it to your pictures folder. You cannot copy and paste any type of file directly into a folder.
The image has to be opened (with any number of programs such as Windows Picture Viewer or a photo-editing software such as Paint or Gimp).
Usually, depending on your email program, you will see buttons next to the picture that say either View/Download/Save, etc. You can also open/download by simply double clicking the image, and it should open for viewing with your default program. From there, you tell it to save and where...
Once it opens, you simply save it to your destination.
From there you can organize and also upload the image to sites that host files and create slideshows.
