That sounds like it should work.
As a Test:
Hold down the option (or alt) key and launch iPhoto. From the resulting menu select 'Create Library' and make a new Library on the device.
Import a few pics into this new, blank library. Is the Problem repeated there?

I did as you suggested with a new library and imported 4 photos and it worked but with some slight delays, especially when closing iPhoto from the pulldown menu but it still worked fairly well. Then I imported the remaining 2,000 or so photos and tried it again. The import process was a bit slow but went smoothly enough but "finishing import" took ages. So now I have a new library with 2000 photos, same as the original library, but strangely enough, the new one is 3gb and the original is 7.6gb. What is that extra 4gb doing, I wonder. However, now the operation is very slow, with lots of spinning umbrellas. So I don't want to delete the original library yet, even though I have it backed up on an external hard disk. Can it be that the usb stick cannot cope with all the data?

Given that the Library works perfectly well on a Hard Disk, it does look like that, doesn't it?
As for the extra data - have you synced with an iPad/iPhone/iPod at any point? It could be the cache generated for that operation.

I have loaded pictures into iPhoto from my iPhone from time to time, so maybe that is it. I repaired and rebuilt the database on the original library and copied it to the stick but it is still slow. There does not seem much more to do. I can still use the stick as long as I don't expect it to be perfect. May test the iTunes folder on it to see how that works. Thanks for your response.

Have resolved the problem and freed up 36gb of space on the Macbook Air.
I discovered for sure it was the USB stick that was the problem. When I moved the iPhoto library that was acting slowly from there onto the MBA it worked perfectly from there. Then I put the iTunes folder (28gb) onto the empty USB stick and iTunes worked without a hitch from there. I had a 32gb SD card, also made by Transcend, and moved the original iPhoto library to that. Presto! it worked.
So an SD card is preferable to a USB stick, at least for iPhoto.
Thanks again for the advice.
