First off, my expertise is in sound, not visual art. I only do graphics work to generate promotional materials. My primary program is an old version of Print Shop because it's easy to use and I'm familiar with it. However someone did give me a copy of Photoshop 7 and every once in a while I try to get some use out of it but mostly I leave it alone because it scares me.
The issue I'm wondering about at the moment is whether it's possible to make a slightly pixilated image not look pixilated, perhaps by smoothing out the edges or resampling or something.
I have a number of promo pictures on my hard drive that I had taken early last year and when I'm promoting a new project, which I'm doing now, I need a different kind of picture and I'm wondering if there's an easy way to doctor these pics.
Any help is highly appreciated.

Neat Image is a free download that does a good job with making pixelated photos look better, you can do a google search and find it easily. Although I only use this program when I have to, I can't seem to navigate it very well -- but it does work. If your wanting to use ps only for this, perhaps you could try to use one of the blur filters. Sorry, I don't have a few more suggestions but maybe this will get you started. Hope this helps you!

I am not the world's best techie but there are a series of free filters from Xero and one of them is for running on pixellated pics. Will try to find the thread for this here. Was discussed just a few days ago. By the way, I ran Xero filters in both PSP and PS so you could use either program if the filter did the trick for you.

Okay, found it, thread is here. Filter is Super Smooth.

Sometimes, the only way to fix a not-so-great image for enlargement is to give it the "artsy-fartsy" treatment. I other words, instead of using a straight photo, make it an illustration based on the original pic. If you cant fix the flaws in what you have, make them look intentional, hahaha.

Another great filter for doing nice fixes on photos is the Optik-Verve Virtual Photographer set. It is one of the most amazing filter sets I have ever downloaded, and its free. I'd have gladly paid green cash money for it.

Its basically a collection of exquisite photographic darkroom/printing effects simulators, all fully tweakable from within the dialog box.

It comes loaded with an impressive collection of pre-sets, and there are more available for download from that same site, but for some reason I can't seem to find the "user-submitted pre-sets" page, good luck.

I agree very much with a previous post that suggests Xero, a wonderful FREE filter set as well. Between these 2 filters, you should be able to turn just about any less-than-perfect photo into a wonderfully stylish illustration.

A great method for enlarging a too-small source image was recently gleaned from Kelby's Photoshop CS for Digital Photographers; Image> Image Size> instead of inches, PERCENT> 110; Bicubic smoother.

Do this in increments of 110% until it is the size you want, THEN apply your "photo to illustration" filters.

You should be able to transform just about any image into a stylish, moody illustration by tweeking the contrast, boosting the color, (or desaturating it) adding some artsy grain, and softening the focus.
