When uploading photos to your childcare.center page, it is recommended to use common image file formats such as JPG or PNG. These formats are widely supported and can ensure that your photos will be displayed correctly on the page.

JPG (JPEG) format is a popular choice for photographs as it can compress the file size while maintaining good image quality. This can make it a good option for photos that have a lot of detail and color variation.

PNG format is a good choice for images that have transparent backgrounds or graphics with sharp edges, as it supports transparency and maintain the high-quality of the original image.

If you are unsure of which format to use, it is generally recommended to use JPG for photographs as they are better compressed and load faster. However, if you have images with transparent backgrounds or graphics with sharp edges, then you should use PNG format.
