sxc.hu is my favorite. Be sure to credit the photographer/link to the profile. Also, a site like depositphotos may require a fee but depositphotos is fairly inexpensive. You may save that for a hub that you really want to craft.
sxc has been a favorite of mine for a long time. Now, I'm getting more excited about flickr, ever since I learned to search for photos in the category I want which are also free to use for commercial purposes. There's a LOT of great stuff there.
Thank you everyone for the great advice. It is really appreciated. Whenever I try to download a pic from sxc it comes out too huge so maybe I am doing something wrong. If I do the right click, copy pic then that is when it becomes pixelated. I have used pics from there on other sites with no problem, but when I upload them on hubpages it comes out pixelated.
The main source of my photos is Flickr Creative Commons. There is a specific search within Flickr for Creative Commons Licensed photos. I have not had any problems with downloading from there with the quality of the photos.
Here's how I download pics from sxc and have them display in HP photo capsules without any pixelation:
Click the orange "download" button that's under the picture you want to download. The full-sized image opens in a new window. When the download is complete, right-click on the image and select "Save image as..."
Sounds like you are getting pixilated images because you are choosing "Save image as" from the small image above the download button, not from the image you download into a separate window?
Oh, they're providing huge photos, but you can slim 'em down to 600x800 or so, small enough that Hubpages' uploader can handle them. If you don't have Photoship, use...er...hang on, what's the name of that site?
Oh, here's one I've seen before, but just Google "resize image" -- there's a whole bunch of free online photo cropping and shrinking tools.
I've never resized a photo for use on HubPages, ever - even Morguefile photos where the file size is huge. The uploader resizes the photo for you. Or maybe I've just been lucky in the last four years...
It is, but notice that it says, "Do not assume that the results displayed in this search portal are under a CC license"
You still have to check the conditions of the license on each photo. I find they're not CC licensed too often, so it becomes a time-waster. The Advanced Search on Flickr is accurate and I can rely on it, so I generally stick to that.
If you have the option, original photos are the best way to go, so try snapping a few of your own shots. Otherwise, Marisa Wright has a great hub about proper use of flickr images that you may find really helpful. Good luck. (And I agree with UW, if the image is pixilated, it is too small either in dpi, or canvas size.)
Whitney05 always seems to include great photos in her hubs, and I'm wondering if she has some tips on finding photos, especially dog photos that are free to use. Anyone else who has tips for such free photos, would be...
One of my big problem is, I do basically nothing with pictures and videos. Because I'm not really sure where I can get them. I am more or less talking about pictures, but if their is some hidden secret with videos aside...
I have trouble when I find a picture to use on Flickr. I see all the symbols and can tell if they need to be attributed or not. But when I try to copy the picture, sometimes I can't. I see a line on other people's hubs...
