I don't have a large number of photos uploaded, but I found that pagesize-0 will return all of them to me in a at once, where they are numbered
1-9
a-z
10-19
1a-1u
20-28....and counting.

Alternately I had put pageSize-9999, but putting in zero seemed to work and felt cleaner (but presumably dangerous if you really have a lot of photos).
