cannot delete pictures from my iphone photo stream there is no trash can to move them to

Open your my photo stream album, tap Select, tap the photos you want to delete, tap the trash icon on the bottom right.

The trash Icon is not available at that point. I can not delete photo stream pictures either

Are you sure you are trying to delete them from your My Photo Stream Album? If you are in this album, as soon as you tap Select, the icons at the bottom (or top left on an iPad) change to the share icon, "Add To" and the trash can icon.

Just recently upgraded to IOS 7.
Clicked photo app
went to photo stream album (there is an <Album button on top left then top right you can choose Select Bottom has a Photo's icon and and album icon) no trash icon
Hit select - pick the photos I want deleted.
Only available courses of action now are to cancel top right
or send by message, mail, twitter etc bottom left
or Add to bottom right
In selecting add to there is no trash available only other albums or a new album.

Is the album name at the top "My Photo Stream"?

No just "Photo Stream"

That sounds like an album that was synced to your device from your computer using iTunes, and the name of the album (or folder) on your computer is "Photo Stream". Those photos can only be removed by deselecting them on the Photos tab of your iTunes sync settings and syncing.

Your photo stream album is called "My Photo Stream".

I never created an album "Photo stream" They were the pictures which at one point I had my photo stream on and had taken photo's and then deleted them and they have not been deleted in this album. I also tried to synch my phone and computer and nothing has changed.

Are you signed into your iCloud account on your computer with photo stream enabled? If so, is it a PC or a Mac?

Yes PC

Figured it out I needed to click sync photos from My Pictures on the itunes in my pc to delete them.

I was just typing this when you replied. What happened is that your PC created a folder called "Photo Stream" automatically when you enabled photo stream on it, possibly on a different PC. This would have been inside your My Pictures folder. At some point you must have synced it to your device, where it was then stranded. Syncing My Pictures again would then delete them.
