How to install themes
This guide assumes that you have installed your MiniGallery at www.yourwebsite.com/gallery, and that you are trying to install a theme called 'newtheme'.
Step 1: Download theme
Download a theme from our themes repository. It will be a zip file containing all the theme files, so once it's finished downloading unzip it onto your computer somewhere, preserving the folder structure - all the files should be in a folder called 'newtheme'.
Step 2: Upload theme
Connect to your web space using an FTP or SSH client, and navigate to /gallery/assets/themes/. Upload the whole 'newtheme' folder to here. You should end up with the new theme sitting at /gallery/assets/themes/newtheme/, and each theme should contain at the very least 'index.php', 'header.php' and 'footer.php', and will mostly likely contain a lot more, depending on the theme.
Step 3: Tell MiniGallery to use your theme
Open /gallery/index.php in a text editor. At the beginning of that file you will see a few configuration options. To change the theme, change $themeToUse to 'newtheme'. Save it and upload it back to /gallery/.
Step 4: Check it's all working
Go to www.yourwebsite.com/gallery and make sure everything is working as expected. You may need to refresh your browser to make sure the images are loaded properly.
