Listing an email address in plain text on a website can lead to increased spam, as bots easily harvest these addresses. To mitigate this, converting the email address into an image is a common solution. This can be done by using the Print Screen function to capture the email displayed on the screen, then pasting it into an image editing program like MSPaint, cropping it, and saving it in a smaller file format like .JPG or .GIF, avoiding larger .BMP files. An alternative method is to directly type the email address in an image editing tool and save it. Other obfuscation techniques, such as using ASCII codes or JavaScript, exist but their effectiveness against spam bots is uncertain. However, if the email address has already been exposed, changing it to an image may not significantly reduce spam, as it may already be in spam databases.
