Most of the product codes I use to promote products include a 1x1 pixel image that is linked to the exact affiliate URL as the text or regular-sized image is.
Next question: Can I safely remove it and still be credited with the referral?
These 1 pixel images, under certain circumstances (especially CSS related), cause design/template problems. I've even had to display:none some of them so they wouldn't wreck my pages. Is setting them to display:none tantamount deleting them from the page?
Can I leave them out completely?
Thanks in advance for helping me with this.
