If you are doing visits, then it is usually best to find the first one and then do nearest waymark from that one assuming you are visiting waymarks in the same area.... or do searches using either the waymark number or name as a key word. WM6KR7 - Royal Oak Theater.... found 2 seconds

I get the waymark description into my gps. I download gpx files load into gsak and create poi's and load into gps. I really don't care what the logging instructions are I know I will be taking a few photos in general.
Photo uploads is a known problem. I typically do photos under 200 kb... even though site will accept larger there is a time out issue.
