I hope someone can help me, I have read so many threads but couldnt find the solutions. I have two issues

1) Only 9 of my 80 images are showing on the home page. Where in the admin can I set this number to be higher?

2) My images keep changing locations everytime I referesh the page and sometimes duplicate images show up on the home page. How can I keep the images in the same order at all times and move them around whenever I want to. I thought I could just add numbers to the images, but that didnt seem to work.

Here is my site: www.divinechishirts.com

Any help would be much apprecaited. Thank you and have a blessed day
