Replying to Weird photo search

hey guys,

I have been searching photos for an article and I came across something weird with photos. Is it correct you cant search photos in all categories? Im finding you have to pick a category first. Not a huge problem but when im looking for pictures of the glacier Im having to search in a few categories rather then one search.

I also found if I search then click on a pic then click back it clears the search and I have to start again.

These might be known things but I just thought id mention it
