I am adding my gif images from my old phpBB forum. When they in they shrink down. Checked the size icon is set to zero. If you go to this forum you will see:

Attached is also a picture showing how small they are. Compared to the default ones they are about half the size. They are so small you can't see what they are.
Thanks for your help on this.
