This is wrong:
size_t *output_length; // declared an indeterminate pointer
lobi = base64_encode(buffer, fileLen, output_length); // sends bogus address
It should be
size_t output_length = 0; // note *NOT* a pointer
lobi = base64_encode(buffer, fileLen, &output_length); // note address-of operator

When should I use Base64 instead of normal image files?
If your project requires you to encode image to base 64 frequently, keep the files small to avoid bloating your HTML. Base64 is ideal for small icons, logos, and embedded UI elements in emails or HTML. It should not be used for large, high-resolution images since Base64 increases file size by about 33 percent.
