Is it possible to use the same image as the main image as your thumb just a scaled down version without using the resizing program. I have a website that is getting the images dynamically and it is working fine. The only problem I have is the images that it shows in the thumbs is a severely cropped image of the main image. How can I scale that image to 25% before it crops it? I see in the image code there is a width and height but doesn't seem to do anything on the gallery.

Also I want to do a similar thing with the main image. I would like to set a standard width like 600 and all the images that display in that main window will show in the width of 600 and the hight will keep aspect to the 600 width. So if a image is to large it will bring it down to 600 and if a image is to small it will display it at 600 as well. is this possible? I have not had any luck getting it to do this.

Thanks

Hello Rusty,

You say you are getting images dynamically. Do they pass through a Smart Image Processor or a similar script?

No they do not. The thumb and the main image are the same file. I just want to display the thumb much smaller not cropped.

Hello Rusty,

Unfortunately you can gain a little control over the thumbnail images in CSS Image Gallery, because they are set as a css background-image property. Despite that the main image is not populated in such a manner and you can have there an additional CSS adding :

.imageMainContainer>img {width:600px !important;}

This will set each main image to 600 width and will keep aspect ratio.
However you must not set gallery to auto resize to fit the image.
About thumbnails... you'll need a image processing script or set the dimensions of the thumbnail container bigger.

Hello Col,
You need to set in the css style of the next and prev buttons outline:none
Also you need to apply this property to .dmxGallery class style.

Scaling images up to 25% before cropping:
You can use CSS to scale the image up to 25%. Assume you have a class that applies to finger images.
.thumb-image {
max-width: 25%;
height: auto;
}

This will scale the image to a maximum width of 25% and preserve the aspect ratio.

Main image with fixed width:
To set the default width for the main image, you can also use CSS.
.main-image {
width: 600px;
height: auto;
}
This will change the width of the main image to 600 pixels, the height will be calculated automatically taking into account the proportions.

To ensure these styles are used on your images, you need to add the appropriate classes ("thumb-image" and "main-image" to the appropriate HTML elements.

There are a few ways to approach this:

For the thumbnails, you can scale down the full-size images before generating the thumbnails. For example, in PHP you could load the image, use the imagescale() function to resize to 25% width/height, then crop and save the thumbnail version. That way it scales first instead of cropping at full size.

For setting a max width on the main images, you can use CSS styles to enforce this. For example:

css

.main-image {
max-width: 600px;
height: auto;
}

This will scale down any images wider than 600px to fit, but allow smaller images to display at their native size. The height scales automatically to preserve the aspect ratio.

Alternatively, you could resize the images on the server before serving them. In PHP using imagescale() again but setting just the max width and height auto.
