Take a look at Zenfolio as well.  I have the pro account there and it's loaded with features.

SS in my experience is definitely one that needs to be continually fed in order to keep  steady earnings there.  I'm not producing a heck of alot of stock imagery these days (8-10 images/ week) and it seems like SS needs about 20 or so quality images/ week in order to maintain decent sales.

Well for one I have better equipment because of microstock because I've earned enough money to finally get a decent DSLR and lenses.  I'd say "better" on the technical end since I pay more attention to making sure my images are clean, sharp and well composed.  On another hand though I'd say I'm a "different" photographer because of stock and have even changed my outdoor pursuit habits as a result.
For example, I used to go on hikes just for the sake of going on hikes, but now I choose hikes and other destinations at least in part by their "stock value".
I used to do more fine art orientated photography, but now not so much anymore because stock pays better.

Ah yet another reason (as though I needed one) not to live in the U.S.!

I think I would go to Canada though it might be too cold for my hubby in the winter...

All depends on where in Canada you are talking about.  The west coast where I live has a similar climate to that of Seattle.

I shoot mostly landscapes too and get alot of landscape rejections.  I would think however that your Mt. Ranier shot would sell to some degree, but again, microstock in general doesn't place a high priority on such images unless it conveys some kind of concept.  Now if you had a tent in there or a young hiking couple holding hands and enjoying the scenery it would be more marketable as a stock image.
In my nature and landscape stock photography I try to get some sort of a human element into the image.
Sometimes I'll even do a dayhike and carry along a tent and a few camping props to quickly set up, take a few shots, and then pack up again. 
Don't take rejections personally as they're reviewing purely on the basis of a "will it sell here?" mentality.

Image requirements:

What are the technical requirements for submitting to Veer Marketplace?
Our technical requirements for JPEG photos or illustration:
- minimum pixels = 1200 x 1600 (approximately 4� x 5� at 300 ppi)
- preferred pixels = 1920 x 2560 or larger (the larger the better!)
- maximum file size = 20 megabytes (compressed file size)
- sRGB or Adobe RGB 1998 color profile
- JPEG format saved at highest quality (lowest compression level)
- Balanced highlights and shadows (RGB shadows no lower than 5, highlights should not be higher than 250)
- No interpolations

Minimum payout is $100.00
I didn't see anything about a minimum amount of time that a submitted image had to remain on the site like what DT and BigStock have

I made the mistake of buying Cushystock, but at least it has a useful keyword generator.  What I've been doing now is in the Lightroom Library module I go to the "Label" line and add in abbreviations of where the given image has been uploaded, so a label for an image might look something like "SS DT StockXpert IS" and so on. 
That way I can tell through Lightroom what images have been submitted where.

I recently purchased the latest version of CushyStock and am having problem after problem with the software.  I scan my working folders but then they don't show up and just ask for me to scan them again, Shutterstock is the only port that with import into cushystock; IS, DT and StockXpert won't import at all.
I did a full re-install after it crashed with the first install and subsequently refused to reload. 
At least the Cushy wizard seems to work and the keyword generator is great.
I emailed Cushy admin and they just suggested to do a reinstall, which I've done, but the current installation is worse than the former.
Anybody else have trouble like this with Cushy Stock?

I haven't had alot of success with 123RF, but then perhaps I never gave them a fair shake (only about a 50 image test port). I currently have 4 agencies that are paying me enough to make it worth my while, so I don't know if I'd want to add a 5th.  Funny how others say that sites like StockXpert aren't doing well for them, but for me it does alright (600 image port for me over there).  IT all seems relative to your port content.

I started out with Olympus as well (E-500) then moved to an E-510.  Last year I sold my Olympus stuff and went with the Sony A350.  Now I also bought a Sony A700 and use the A350 as a backup or whenever I want something with a live view and tilting screen.
I particularly love the Sony's for all that nice Minolta AF glass still out there at great prices.

You can also do an HDR blend out of a single image, which is a technique I employ more often than doing multiple exposures.
My general method is to take a single RAW image and generate 3 images; one underexposed by a stop, the original exposure, and one overexposed by a stop and toss the three into my Dynamic Photo HDR software.  That's what I did with the above semi image as well as this one which will be hitting flame status on Istock soon:

My only official flamer and seems to be popular around this time of year.  Last year it got me close to flame status and this year when easter started getting close, sales picked up again.



This next one isn't at flame status just yet, but I'm sure it will as it's been getting almost daily sales for the past few months:



I suppose it's a good seller as it's just as much or moreso a conceptual shot as it is a shot of the sport of orienteering.  I ran this image through HDR software to get the look I wanted before submitting it.
