I have some photos in my personal profile that I want to put on another page on the website. How do I move them?

You have two options:

1) While viewing your photo, right click on it, select copy, then open up an editor page and press paste. The only disadvantage to doing it this way is if you ever delete the photo from the Profile, it will also delete from wherever else you've pasted it.

2) If you want to avoid the problem above, just upload a second instance of the photo wherever you want it.

I have 290 photos. I want to import them all at once, can I do that?

Depends. 290 photos makes for a huge gallery. Personally, I would break that up into logical groups of smaller 50 - 60 picture galleries. Organize them into folders on your computer. Then, when you go to upload the photos, you can do a CTRL A to select all the photos in that directory, and click open or select (depending on the browser type) to begin the upload. They will upload in bulk by this method. Can you do all 290 at once? Yes, but I think this other method is easier.
