FAQ:
Why is my image not uploading?
If you're having trouble uploading an image, it may be because your file is too large. All image files must be under 10MB to be uploaded to your PublicInput image library. It's best to check the image's size before trying to add images to your library.
Why is my image blurry?
If your aspect ratio and pixel size match PublicInput's recommendations but the image appears blurry, the image resolution is likely too low for the display size. Starting with a higher-resolution image and using image editing software to resize/rescale images properly will help reduce the likelihood of blurriness in photos.
Can my icon be a circle?
Yes. The icon can be a circle within the square, however it is still recommended to maintain a 1:1 aspect ratio. If you are using a rectangular shaped icon, please use a minimum dimension of at least 200 pixels.
Why can't I paste images into my project?
There is no limitation to the file size that is accepted when pasting and it can consequentially cause extended load times and the loading to eventually fail altogether.
What's the difference between .jpg .jpeg and .png?
.jpg and .jpeg can be used interchangeably and are the same. .Jpg (.jpeg) is best for photographs and images with complex colors. .png is best for images requiring transparency, logos, icons, and images with text.
What file type should I choose?
Choosing between JPEG and PNG depends on the specific needs of your project. Use JPEG for photos and images where file size is a concern and high levels of detail are not important. Use PNG for images that require transparency or where maintaining high image quality is important.
