Help Will Boot image affect the bootloader on Verizon GS3 using safestrap?

[bjf18]

hello i have the verizon prepaid galaxy s3 and i have a rom called "Wicked Sensations V0.5 now i opened up the zip file to see what all it had and i noticed it has a boot.img but the Alliance rom does not have a boot.img. The wicked sensations rom says its knox free though. i was just wondering beings it has a boot.img in the sensations rom, will that affect the bootloader any? or is that just like a start up image that the developer made like a picture? also im installing using safestrap. so could anyone shed some light on this quick question? much appreciated!
