PDF creator, please

[Detritus]

In other words, I'm rather desperately looking for an alternative for Acrobat (too expensive, too heavy) to create pdf files from jpg/bmp images. I've tried a number of them but either they add watermarks or just don't deliver what I need, one even almost killed my 'puter( forgot which one). Closest thing to make it was Foxit Creator but either I didn't understand the manual or there's something funky about it, because I only get a part of an image edited to pdf. So, if someone has an idea for a good creator, PLEASE let me know. This is pretty important.
