General Support: cant get more than 20 pictures on a gallery??

so I thought I'd try this thing out..have been looking for a different gallery than I have been using...
I have albums that have over 100 pictures in them...and have probably about 40 gallerys total roughly
when I upload all of them and I go to that album I can only see the first 20 of them...
I need it to build over 100 thumbnails on the main thumbs page...not make multiple pages(which it doesnt do that either for me)
so right now I'm stuck with 20 thumbs...I can click the 20th one and hit next to get to the ones past it...but I cant seem to find what I need to change to show more than 20 thumbs

basically....
main menu....click
thumbnail page.....I only see 20....with my screen resolution its 2 rows of 9 and the 3rd row has 2 in it....total of 20 thumbs
if I click any thumb...it goes into the small view mode where the pic is resized and fits your screen.....if I press the next button I can get past the 20th one that I can see on the thumbnail page..I can see all of my pictires if I use the Next pic button...I just cant see more than 20 on the thumbnail page
