Can't Add Media ( Images)

I have tried several times to add a few pictures and each time I am told there is a server error and to try again later.

Yes, it is the first time I've attempted to do this here but it's not a difficult process and I don't think I did anything incorrectly. Five images are waiting to be saved and if I forget again and close the tab, I'll have to do it all over. again.

I tried a few times yesterday to save and finally gave up. I tried again just now, on two different browsers, with identical results.

I wanted the images to be available for the plant database, but if I can't save them,, that's not happening.

What's up?
