the current displaying of search results makes it harder to get sales

No need to spam post in all threads. Everyone will just get tired and ignore future posts. Everyone agrees with you and P5 has given answers to this many times. They have done what they want to their web site. Agree it's too difficult to figure it out on how to turn it off and like you have said, we as sellers don't like it and I seriously doubt buyers like it at all. Especially after getting to single page results but hitting back makes them start all over again.

ive been getting on pond5 on and off for about a year
and a half and i never noticed the turn-off option.
it's completely unintuitive.

i know i kinda spammed all over the place, but this is
a big issue, why should i keep my mouth closed so as
to not bother ppl?

i believe its worth bothering about this.

Even I choose "Sort By: " the "Load more Results" is still there. It is annoying, really....
Please fix it.
