To solve this, we have built a component for Joomla CMS that makes it very easy for our customers (and now yours!) To customize images. Crop and reduce the file size of individual images or create profiles that can be used over and over again. Ideal for pages where you want the same format for all images, such as product images or news blogs.
Upload your own image or download free images from Unsplash.com directly in the component. Preparing perfect images for your website has never been easier.
Nothing demonstrates this better than a video (an image may say more than 1000 words - but what does not say a 7 minute video !?)
