Hi Jerry
No problem at all. We all those "moments".
OK. In iPhoto select the 44 photos. If they are in sequence, Left Click on first and then holding down the Shift key, click on the last. That will select all photos between these two points. If the photos are here & there, choose them by holding down the Command key and then clicking on each one in order.
Now that you've chosen the photos; Go to the top menu bar and Click File > Export. This will open a drop down menu. Kind = JPEG. JPEG quality (choose between Low, Medium, High, Maximum). Size: (choose between small, medium, large, full size). Click Export. This will open up a box. Now choose where you want to copy the images. (If you can't navigate to your thumb drive, can't find it, whatever; just choose Desktop and hit OK. From the desktop you can drag them to your drive).
Please report back on success or otherwise.
Ian
