Image Options

| Property | Type | Description |
|:-----------------|:------------------------|:-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| src | string | Required. A string referring to any valid image resource (file, url, etc). |
| width | number | Required. Width of the image. |
| height | number | Required. Height of the image. |
| nano | string:base64 | Optional. Thumbnail Base64 image will be injected to background under the main image. This provides a base64, 4x4 generated image whilst the image is being loaded. |
| alt | string | Optional. Image alt attribute. |
| tags | array | Optional. An array of objects containing tag attributes (value, title and key if value is element). e.g. {value: "foo", title: "bar"} or {value: {tag.name}, title: tag.title, key: tag.key} |
| isSelected | bool | Optional. The selected state of the image. |
| caption | string | ReactNode | Optional. Image caption. |
| customOverlay | element | Optional. A custom element to be rendered as a thumbnail overlay on hover. |
| thumbnailCaption | string | ReactNode | Optional. A thumbnail caption shown below thumbnail. |
| orientation | number | Optional. Orientation of the image. Many newer digital cameras (both dSLR and Point & Shoot digicams) have a built-in orientation sensor. The output of this sensor is used to set the EXIF orientation flag in the image file's metatdata to reflect the positioning of the camera with respect to the ground (See EXIF Orientation Page for more info). |

Gallery Options

| Property | Type | Description |
|:------------------------|:--------------------------|:---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| images | array | Required. An array of objects containing image properties (see Image Options above). |
| id | string | Optional, default ReactGridGallery. id attribute for tag. This prop may be useful for those who wish to discriminate between multiple galleries. |
| enableImageSelection | bool | Optional, default true. Allow images to be selectable. Setting this option to false whilst supplying images with isSelected: true will result in those images being permanently selected. |
| onSelect | func | Optional. Function to execute when an image is selected. Optional args: index (index of selected image in images array), image (the selected image), event. This function is only executable when enableImageSelection: true. |
| rowHeight | number | Optional, default 180. The height of each row in the gallery. |
| maxRows | number | Optional. The maximum number of rows to show in the gallery. |
| margin | number | Optional, default 2. The margin around each image in the gallery. |
| onClick | func | Optional. Function to execute when gallery image clicked. Optional args: index (index of selected image in images array), image (the clicked image), event (the click event). |
| tagStyle | func | CSSProperties | Optional. Style or function that returns style to pass to tag elements. Optional args: item (the image item in images). Overrides internal tag style. |
| tileViewportStyle | func | CSSProperties | Optional. Style or function to style the image tile viewport. Optional args: item (the image item in images). Overrides internal tileViewportStyle function. |
| thumbnailStyle | func | CSSProperties | Optional. Style or function to style the image thumbnail. Optional args: item (the image item in images). Overrides internal thumbnailStyle function. |
| thumbnailImageComponent | React component | Optional. Substitute in a React component that would get passed imageProps (the props that would have been passed to the tag) and item (the original item in images) to be used to render thumbnails; useful for lazy loading. |
| defaultContainerWidth | number | Optional. Set default width for the container. This option is useful during server-side rendering when we want to generate an initial markup before we can detect the actual container width. |

* react-grid-gallery is built for modern browsers and therefore IE support is limited to IE 11 and newer.

* As the inspiration for this component comes from Google Photos, very small thumbnails may not be the most aesthetically pleasing due to the border size applied when selected. A sensible rowHeight default of 180px has been chosen, but rowHeights down to 100px are still reasonable.

* Gallery width is determined by the containing element. Therefore your containing element must have a width (%, em, px, whatever) _before_ the gallery is loaded!

* If you don't know your width and height` values, you can find these out using any number of javascript hacks, bearing in mind the load penalty associated with these methods.
