Surely, you would like to add images to your website. Whether they are placed in the content of your pages or used in templates or photo galleries, they have to be uploaded to your web host first. You should optimize your images before displaying them on your website. Do not upload images that are larger than 200KB. This restriction is not from CMS Made Simple. You can upload and display even larger images with Image Manager. The restriction is suggested in consideration of your visitors who want your website to load quickly. If you use large images, your website will load very slowly, and a certain percentage of your visitors will close the browser before they have seen what you offer on the website.
Note
The rule of thumb
One image should not be larger than 20KB and all images on one page together should not account for more than 200KB.
Resize your images with graphics program before using them on the website. Or, use the built-in image editor in CMS Made Simple to resize...
