With our widget "Image Gallery" you can easily create a nice gallery for your website.
Go to the content editor on the page, where you want to put a gallery. Open the tab "Widgets" and click "Image Gallery". Then select a folder with images from the dropdown list (how to upload images to your website you can find here). Choose the options for your gallery:
Thumb. size - width of the images for the gallery
Crop image - you can check this box to crop the image and the hight of the image will be the same as width.
Caption - you can display the name of the image (don't forget to put sensible names for your images)
