Images are good value with credits costing 50c or less if you buy bulk. There is also a subscription option, with a weekly 70 images subscription currently at around 35 dollars.
The site has been slowly gaining market share since 2004. It is very pleasing to hear recent news of affiliation with fotosearch, this will hopefully increase sales levels, which are at the moment quite low.
Good statistics monitor photograph views and an itemised history of sales. Since the affiliation with fotosearch the upload system has been streamlined, and sorry to use the cliche but there is no better way to say it, "uploading is a breeze" there is no need to spend time categorizing images.
For the photographer commissions are average, at the at time of writing this sales are quislow. The site features good stats and sales reporting tools.
Further to my previous comments on photos all being rejected with a standard "* Image does not meet our current content submission standards." it's been pleasing to see that recent submissions now receive useful rejection reasons which can help photographers reduce future rejections.
Conclusion
Slow sales but with the recent fotosearch affiliation things are improving. Canstock is not a priority for upload, but not one to write-off either. Canstockphoto has potential, so for the moment I'm still uploading and measuring results.

Fotosearch is one of the largest stock photography agencies in the world and a true innovator in the industry. As part of the new relationship, Fotosearch will distribute Can Stock Photo imagery, which will provide access to the substantial worldwide network Fotosearch has built over the past 10 years, and afford Can Stock Photo contributors the opportunity to generate more revenue. Fotosearch boasts the largest network of non-English stock photography sites in the world, with sites localized for 47 countries. Introduction of Can Stock Photo content will begin on the Brazilian and Japanese sites, www.fotosearch.com.br and www.fotosearch.jp, with more sites to follow. Once the content is fully rolled-out, Can Stock Photo contributors will be exposed to millions of Fotosearch visitors every week. Through Fotosearch, contributors will be able to sell images as prints, and Fotosearch will soon have a program to include the best content in a professional brand. Your images will continue to be available at www.canstockphoto.com, and the payout structure for imagery licensed there will remain the same. Licensing on Can Stock Photo has been streamlined from five options to simply a standard license (limited to 500,000 reproductions) and enhanced license (with either unlimited reproductions or items for resale), to be more in line with industry standards and to encourage enhanced license sales.
