Thank you sincerely for your prompt and thorough reply. I believe I attempted a CENTER align option initially but things didn't work out. For some reason, it was significantly increasing the spaces between the buttons on the left, at least on my home page. I just played with the sizing numbers until things worked out. That said, I'll give it another try.
Yeah the code duplication wasn't a problem since I just deleted each duplicated code from the folder it was saved into, and kept the correct codes in their respective folders. No issues. Basically, I have a folder for each "gallery" on my page: Portraits, Commercial, Maternity, etc. Within each folder, there's the actual HTML page, images and thumbnails, and juicebox code. I name the code the same as the gallery (ie. Code_Maternity.html).
What was happening was, after finishing the code for one gallery, I'd move to the next folder/gallery and save the respective code into it. So, if I just finished Code_Maternity.html and then went to the portraits folder and saved Code_Portraits.html, the maternity code was duplicated and saved in the portraits folder as well.
By the time I was finished with the last gallery (landscapes), there were codes for all the previous galleries stored in the landscape folder (ie. Code_Portraits.html, Codes_Maternity.html, Code_Children.html, etc.).
At first I thought maybe juicebox needed all the codes stored in one folder. But after deleting the excessive codes and seeing that my site functioned appropriately, I thought maybe it was a glitch in the program. Or maybe I was doing something wrong.
