Is there a way to know if the file extension is an image?
i got this.
image/png
Already try with
var imageReg = /.(gif|jpg|jpeg|tiff|png)$/i; string = "image/png" imageReg.test(string)
But this return false;
Answer
Put dot and / inside a character class so that it would match .png or /png strings.
var imageReg = /[/.](gif|jpg|jpeg|tiff|png)$/i;
Your regex would return true if there is a dot before png but here there exists a forward slash, so it fails.
