I just wanted to post an update. I have been continually reading and researching color management ever since this discussion started. Apparently there is a LOT to learn about it. Some information that I have gathered may be of interest to all of you, so I wanted to share it before I forget it myself.
The first thing I had to realize, and that I found a lot of misleading information about; was that very few Windows program are color managed. Which means that they don't recognize or use a color profile or work in a color space that we would use as part of our color-managed workflow. sRGB is a color space that seems to be quite broad in its use, but Internet Explorer and most other common Windows apps DO NOT use it. They run off Monitor RGB, which can be close to sRGB, but it really just depends on where the monitor's original color space is. In my instance (and I suspect in Marian's), sRGB and my Monitor RGB are quite different. Therefore, in order for us to predict what we will see when we open an image in any Windows application, we should be soft-proofing those images in Monitor RGB. This would, of course, pertain to any images posted on the web. We would still benefit by leaving the sRGB profile embedded in the file, because Macs have a largely color managed system, so anyone viewing them that way would see the image with the sRGB profile applied. The problem, of course, is that if you make major changes to your image so it looks good with MonitorRGB soft-proofing, it may look way off when viewed with color-managed software. So there may need to be decisions made based on your good judgement and who you plan on showing your images to.
Photoshop is a color-managed software. Therefore, it will show you your images as they need to be for the printer. Again, Adobe RGB has a wider gamut, meaning it can calculate and utilize more colors and variations. Therefore, AdobeRGB is often the recommended space to use as a Working Space while you are editing your images. sRGB is very universal, and seems to be almost standard for many inkjet printers. The printers have their own profiles, but they make the conversion for you. You just need to have a good color space that has a gamut within the ability of the printer profiles. Then, the printer software (in theory) can translate the sRGB profile to whatever profile it actually uses to print the image.
So, my own issue with my posted images, is that I need to soft-proof to my MonitorRGB before posting to the web in order to make sure it renders the same as what I see. At the very least, I need to know what things are going to be different when I post it to the internet. As for my printing, well... all I can say is this, "DO NOT BE CHEAP ON MONITOR CALIBRATION SYSTEMS!!!" Do I need to repeat that? I have been cheap twice now, in total I have spent $250 on two different monitor calibration systems. Neither of which will do what I need them to do. I am now looking at spending another $250-$300 for a good system that will produce acceptable results. It will cost me twice as much now, because I tried to scrimp in the beginning. Live and learn for me; but you should all learn from my mistake (if you don't already have a system working for you). There are a lot of things you can probably get away with by not buying top of the line, but monitor calibration is not one of them. At least not if you want to know, without a doubt, what your prints from the lab will look like.
Also, just so I'm not harping on these systems, they may work great for you depending on your lab. If your lab is doing a final retouch on your images before printing, then you are good to go. If they are printing straight from your files, beware.
